Three dimensional numerical analysis on dynamic mechanical property of tungsten alloys

Dynamic behavior of tungsten alloys under impact loadings was investigated by using numerical simulations. Three dimensional finite element unit cell models with typical micro-structure of tungsten alloys were established. The dynamic mechanical properties of tungsten alloys under tensile loadings were investigated by numerical simulations. The effect of strain rates on the mechanical properties was analyzed. The stress and strain contours of the unit cell model at different strain rates were given. The reliability of the finite element models was verified through the comparison with experimental results.
