The Model of Specimen Transverse Inertia Influence on Testing Result of Dynamic Character of Rock

Abstract:

Based on the assumption of one-dimensional specimens and stress distribution hypothesis，SHPB experiment is used to analysis dynamic characteristics of materials. But it is impossible for the transverse inertia and the friction on the surfaces of specimen. A model is established in order to evaluate the degree of influence of horizontal specimen inertia and friction on the experimental results. Moreover, the model is applied to discuss the transverse inertia effect influence on elastic modulus of materials.
