Numerical simulation of dynamic shear tests for high-strength steels specimens
A series of numerical calculations using the finite element method was carried out to develop a dynamic shear testing method for high-strength steels specimens. The shape of the specimens with two shear zones was chosen for investigations. Obtained results made it possible to choose the optimal specimen size and loading scheme for realizing pure shear conditions. Using the Johnson-Cook model, taking into account the effect of the strain rate, the fracture of the specimens of armored steel Armox 500T was simulated using the appropriate fracture criterion. Obtained results showed that such a specimen design and loading scheme should ensure the implementation of pure shear conditions.
