Abstract
The plate impact experiments have been conducted to investigate the dynamic behavior of
91W-6.3Ni-2.7Fe. Lagrangian analysis technique was introduced to discuss the mechanical properties
of the tungsten alloys under high strain rate and the stress-strain curves of the tungsten alloys were
given. Based on the experimental observations, the three-dimensional finite element models of
projectile and tungsten alloy target are established by adopting ANSYS/LS-DYNA, Dozens of cases
were performed to investigate the dynamic mechanical behavior of tungsten alloy target under impact
loading. A good agreement between numerical predictions and experimental results was obtained,
which suggests that the finite element model is efficient and credible to simulate the mechanical
properties of tungsten alloys.
