FAILURE MECHANISM OF TUNGSTEN HEAVY ALLOY FOR MOULD

摘要：

The failure mechanism of tungsten matrix composite was studied with microscale numerical simulation.The results show that high strength tungsten particles are the real loading elements of composite, its strength level embodies the whole property of the composite to some extent.The real stress in tungsten particles is much higher than the external load, so failure may take place when the external load is less than the theoretical strength of tungsten particles.
