This paper addresses quasi-static loading of the shear compression specimen (SCS), that has been especially developed to investigate the shear response of materials at various strain rates. Previous work [4, 5] addressed bi-linear hardening materials, whereas the present work concerns parabolic hardening materials. The investigation is done numerically using three-dimensional elastoplastic finite element simulations. The analyses show that the averaged von Mises stress ((sigma) over cap (eq)) and strain ((epsilon) over cap (eq)) on a mid-section of the gauge reflect accurately the prescribed parabolic hardening model. A method for finding the parabolic hardening coefficients and reducing the measured load, P, and displacement, d, into equivalent stress (sigma) over cap (eq) and strain (epsilon) over cap (eq) is. introduced and tested. A very good agreement is observed, thus confirming the potential of the technique. for large strain testing of parabolic hardening materials.
