It is used to develop features and goals for product and process, in identifying critical of product/process factor, designing customaries the potential problems, establishing the control to prevent the errors and prioritizing the process submit to ensure reliability. FMEA most commonly applied but not limit to design (DFMEA) and manufacturing process (PFMEA). Design failure mode and effect analysis (DFMEA) identify the potential failure of design before they occur.DFMEA then goes to establish a potential effects of the failures, there causes, how often and when they might occur and their potential seriousness. Process failure mode and effect analysis (PFMEA) is systemized group of activities intended to recognized and evaluated the potential failure of a product/process and its effect .indentify action which could eliminate or reduce the occurrence or improve the defect ability, document the process and track change to avoid the potential failure cause. 2.2 FMEA approach FMEA is carried out by a cross-functional team of experts from various departments.
Advantages 5. Drawbacks Incremental Testing, also known as Incremental Integration Testing, is one of the approaches of Integration Testing and incorporates its fundamental concepts. It is like a test which combines Module and Integration testing strategy. In Incremental Testing, we test each module individually in unit testing phase, and then modules are integrated incrementally and tested to ensure smooth interface
The control charts have a center line, upper limit line & lower limit line. The center line function is basically the process average or expected value. The upper & lower limit values can also be changed by the user if they see fit to do so. The users can signal the need for corrective action by measuring the process sample in accordance with the control plan. They then can use the record function by recording the data on the control chart & plot points that need further attention.
…… … Until 1960s the term research and the term design "was known" as an independent science. Research is Systematic investigation into a problem or situation, where the intention is to identify facts and/or opinions that will assist in solving the problem or dealing with the situation and Design is wide science, includes learn the process of human centered problem solving from the perspective of Industrial Design. If the design combines with research it gives a Design Research! So, what is design research? Why it uses?
Structured walkthroughs is one of the technique used for testing, Walkthrough involve: • Certain classes of inputs are selected and then the actions of the system for that class of data are traced through the design. Design inspections are similar but differ from structured walkthrough in several respects. Design inspections induce substantial improvement in quality and productivity through the use of formal inspections of the design and the code .The design and inspection process can be summarized as first, describe the program development process in terms of operations , and their define exit criteria which must be satisfied for completion of each program. Second, separate the objective of the inspection process operations to keep the inspection team focused on one object at a time .The various steps involved
The necessary information required for the project like material properties, type of load to be applied, intensity of load is taken from the textbook ‘Strength of Materials ’ by Dr. R. K. Bansal. We will simulate our chain link by applying load in ANSYS and study the stress distribution (on circular portion as well as straight portion of the chain link). Assumptions: While finding out the value of stress analytically, we have made certain assumptions. We have assumed that the stress in certain regions is constant which will not be the case in the actual system. We have made sections like the inner part of the circular region, outer pat of circular region, inner and outer part of straight region.
In hypothesis testing, the ANOVA, T-Test, or Chi-Square is used to investigate if a hypothesis’s mean is true or false. Hypothesis testing involves developing the null hypothesis, choosing the suitable test static, identifying the statistical significance, deciding the decision rule to reject or not reject the null hypothesis, and collecting the data and completing the required calculations. The null hypothesis is simply a statement, which the investigator comes up with, that is being tested. Static testing involves using a value that is consistent and is computed from the data, such as the mean or mode. It measures the similarity or dissimilarity between the data and the null hypothesis.
