Abstract

The microstructural characteristics of original textured tungsten samples are certified. The free surface velocities of the samples were measured in shock-wave experiments. The dynamic yield strength and spall strength values are determined for samples of various thicknesses. Mathematical modeling of the performed experiments is carried out within the hydrocode algorithm, in which original equations of state, an elastoplastic model, and an instantaneous spall approximation are used. The reliability and predictive capabilities of simulation of the physical and mechanical behavior of textured tungsten under conditions of shock-wave compression and high-speed tension are discussed.
