SHPB TECHNIQUE FOR IDENTIFICATION OF COMPLEX MODULUS UNDER CONDITION OF NON-UNIFORM STRESS

Summary An SHPB procedure for non-parametric identification of the complex modulus was developed without assuming equilibrium or axial uniformity of the states of stress and strain. It was applied to testing of polypropylene with bars made of polymethyl methacrylate and aluminium, and it was compared with the classical SHPB 1-wave procedure
