Abstract
The report reports a review of basic terms of the Split Hopkinson pressure bar to study the dynamic behaviour of materials under dynamic condition. The FEM method and AQAQUS/CAE are used for modelling and simulation of modified Split Hopkinson pressure bar.
Keywords: Split Hopkinson pressure bar, Dynamic loading, Stress-Strain behaviour, FEM modelling.

Introduction
The Split Hopkinson pressure bar is one of the …show more content…

All the bars must have a straightness of 0.1 mm/m or a value lesser than 0.1 mm/m. Essential fittings for incident bar and transmitter bar should be provided for assisting compression and tensile mode of testing and also, to live a high stress rate, high temperature testing. Strain gauges should be mounted suitably on Incident bar and a transmitter bar to measure the strains generated during testing.

Aim and objectives of work
Split Hopkinson pressure bar in most versatile apparatus for regulating the active behaviour of materials. To get a simple FEM of SHPB and numerical analysis was borne away in the present investigation and to simulate dynamic compression response based on quasi-static test to amount the mechanical response at high line rates and examine the dynamic compression properties, i.e. energy absorption and compressive force at advanced strain rates, to improve full scales stress-strain curves at altered strain rates and to examine the strain rate behaviour of differing materials.

 Modelling and test various geometries of specimens.
 Compare the experimental value with numerical test result values.
 Modelling and simulation of Split Hopkinson pressure bar (Kolsky bar) set up.
 To study the stress, strain behaviour and stress wave propagation in the
