摘要：
The mechanical characteristic and fracture behavior of tungsten alloys 91W-63M-2.7Fe were investigated by numerical simulations. Firstly, the 2D finite element model of a unit cell for the tungsten alloys was given and a multi-particle model was established based on the unit cell model. Dozen of cases were performed to simulate the mechanical behaviors of tungsten alloys with different microstructures. Secondly, the random model of the alloys was established. The fracture behavior of the alloys under different strain rates were investigated by the model. Finally, the relationship between the fracture behaviors of tungsten alloys with the micro-parameters was analyzed.
