COMPUTER MODELLING OF ELASTIC-PLASTIC DEFORMATION OF POWDER POROUS MATERIALS UNDER PRESSURE TREATMENT

Gorokhov V.M., D.Sc. in Eng., the Institute of Powder Metallurgy of the NAS of Belarus

There have been obtained physical and mathematical models for irreversible forging of powder materials to get structural machine parts. The constitutive equations for determination stresses strain rates and density inside a volume of porous body taking into account elasticity and plasticity have been derived. There have been represented different applications of the elastic-plastic model for computer modelling of calculating powder porous composite materials under external loading in a rigid die.
