Hypoplastic Constitutive Model Essay
2.2 NUMERICAL MODEL STUDIES
Constitutive models for soils are usually involving complex equations intended for predictions of the soil behaviour (Ivo Herle, 2008). Besides the objectivity function (independence of reference system and units), they should also include several essential features observed in laboratory tests of soil samples like nonlinearity, limit stress states, proportionality of stress and strain paths, irreversibility and realistic selection of state variables. Constitutive models should be useful not only to their designers, i.e. they must be also user-invariant and different users should be able to obtain same solutions. Hypoplastic numerical modelling is one of the advanced SCL based program developed by Karlsruhe University, Germany. In the following paragraphs, some works based on hypoplastic modelling by different authors are presented.
Masin D (2004) presented a model for clays which is developed on the basis of

This constitutive model expresses the stress increment as a function of given strain increment and of the actual stress and void ratio. The influence of variation in the parameters, such as critical friction angle, granulate hardness, exponents n, α and β, minimum void ratio at zero pressure , maximum void ratio at zero pressure and critical void ratio at zero pressure, of the constitutive model on the oedometric and triaxial response is investigated by numerically simulating the response of the dense sand. Results obtained from the simulation indicate that the parameters such as critical friction angle, granulate hardness, exponent n and minimum void ratio at zero pressure have influence on the oedometric test response and parameters such as critical friction angle, critical void ratios at zero pressure, exponents n and a have influence on the triaxial test

735 Words | 3 PagesThis is the first demonstration which specifies undifferentiated and differentiated cell population in a multiphase HFMB model. In addition, the decent scientific standard of the research is demonstrated through the reasonable assumptions of threshold cell differentiation for shear stress increase, and adequate analyses of expected and resulted graphs with notes to cell cycles and yielding number. The originality is thus classed as high and the priority for publication is high. However, there exists several major doubts.
Susceptible Shortcoming To A Special, Stifling Zone By Dan Greene
495 Words | 2 PagesIn “How Duke Transformed its Defense from a Susceptible Shortcoming to a Special, Stifling Zone” by Dan Greene, the author outlines the sudden transformation of Duke University’s Men Basketball team from a horrible defensive squad into one that is hard to score on. Offensively, Duke is loaded with talent and has many players who are capable of scoring the basketball. However, Defense has been a struggle for Duke this season, causing them to lose crucial games. The author summarizes Duke’s transformation by explaining the influences, advantages, and statistics of the zone defense. Duke has not always run zone defense.
Velma Barfield's Strain Theory Essay
741 Words | 3 PagesFrom Life to ‘Death Row Granny’ What comes to mind when thinking of grandmothers? Cookies, acts of spoiling, and love are just a few, but what does not come to mind may be something like arsenic killings. Yet, in Velma Barfield’s case, one might want to ponder this carefully. Obviously, arsenic poisoning is not something a normal grandmother would be known for, so it is not striking to assume some sort of strain took place in Barfield’s life.
Summary: The Law Of Undulation
580 Words | 3 PagesChrist gives us an eternal joy that nothing on earth can replace, however the demons are constantly trying to sway the patient away from this joy to earthly pleasures. They try to focus his attention on basic things such as reading the newspaper instead of reading his Bible and having a lot of average non-theological conversation (Lewis 22). None of this is technically a sin by itself, but the demons are crafty and distract him with this happiness that looks good. They do this so that they eventually replace the joy deep down in his heart with happiness that will eventually fade. Screwtape enlightens his nephew on the difference between happiness and joy and the uses stating, “Fun is closely related to Joy — a sort of emotional froth arising
1906 Earthquake Dbq
1350 Words | 6 Pages5:12 a.m., Wednesday, April 18, 1906, one of the most devastating earthquakes in the history of the United States hit the heavily populated city of San Francisco, California. This violent earthquake caused extensive and expensive damage and deaths across the city and even resulted in a fire that raged throughout the city for four full days after the earthquake. While the exact casualty tall is uncertain modern scientist estimate the death toll to be around 3,000 people with rough 25,000 left without a home(_____________3________________). However, all was not lost, from the rubble and ashes of San Francisco scientists, seismologist, and geologists alike were able to make improvements upon earthquake technology and better define what causes

General Strain Theory Literature Review
2124 Words | 9 PagesStrain and Deviance: an empirical test of General Strain Theory of in a Philippine Public University LITERATURE REVIEW Theoretical Background During the past decades, various criminologists developed different theories in an attempt to explain the causes of crime within the society. In return they were successful, as of today it was adopted or accepted, indeed all of theories explain the root causes of crime. One of these theories is anomie or strain theory which originally argues that the lower class frustration to higher class causes crime (Merton, 1938) in attempt to explain why majority of the people who commits crime are lower class.

The Mcwhinney Model
921 Words | 4 PagesMcWhinney model of problem-solving (1997) is adopted for solving complex problems of ABC Organisation identified and described in the preceding section. The model relates the complex problem-solving course to the process of the making planned change in the complex problem areas identified to achieve increased efficiency and improved productivity in the organisation. Problem solving is about planning and achievement of desired changes in complex problem areas under consideration and the McWhinney model of problem-solving deals with four realities or “worldviews” of change and six approaches or modes of change. As per the model, these different worldviews or preferred beliefs can be classified into four quadrants namely Unitary, Sensory, social
Merton's Strain Theory
822 Words | 4 PagesThere are many theories that suggest that crime is constructed socially, or is a product of the society in which the crime is committed. One such theory, proposed by Robert Merton, is known as strain theory. While strain theory is a useful model for explaining how societal values can drive people to commit crimes, it has several flaws and does not focus on how laws are made and how this contributes to the formation of crime. While Merton suggests that laws are created from consensus within a society, it will be argued that strain theory can also support the idea that laws are a “product of conflict” (Hagan 5). Strain theory is founded on the idea that the goals of a society and the accepted means of achieving said goal causes strain that can
Essay On Whiplash
832 Words | 4 PagesWhiplash is a neck injury that can occur during automobile collisions, when the head suddenly moves back and then forward. These extreme movements push the muscles and ligaments of the neck beyond their normal range of motion. Causes A sprained whiplash neck occurs when the head is suddenly shaken back and forth or suddenly turned hard. This can cause the abnormal elongation of some neck muscles and ligaments (distortion).
Explain How Does Strain Theory Explain Deviance
1048 Words | 5 Pages1. How does Strain Theory define and explain deviance? Strain theory defines deviance as the situation whereby there exists a gap or difference between societal success goals and the determined means available to the society for achieving these goals. In a society, individuals share similar goals towards success and thus have agreeable means of achieving the same, however, when such an agreement is foregone such a society has a high rate of deviance.
Strain Theory In American History X

The question of which came first the chicken, or the egg conception is the same of learning is too simplistic. Do we truly learn from those who are closest to us who else can we learn from? We should ask the all-time question, “Why don’t we commit crime?” not why do we.
Criticism Of Merton's Strain Theory
1883 Words | 8 PagesCriticism of Merton’s Strain Theory One critique of the strain theory is how it overemphasis the position of the social class in regards to crime and deviance. As we know, the strain theory applies mainly to the American lower class as they struggle the most. Our lower class are faced with the lack of resources to help them reconcile their goals. However, by looking at the variation of deviant and criminal behavior, the strain theory does not adequately account for any type of crimes besides the normal street or neighborhood crimes.
Robert Merton Strain Theory
761 Words | 4 PagesIntroduction The two most important components of societies are the social structure and culture. Culture deeply influences an individual 's beliefs, values, goals as well as his identity. Cultural goals are developed in accordance with the existing social structure of the society. The social structure of a society must provide the 'means ' for an individual to achieve his cultural goals.
