BEHAVIOUR MODELLING FOR MEDIA WITH THE GRANULAR STRUCTURE AT THE DYNAMIC LOAD

Structural-heterogeneous media with the granular structure: polycrystals, composites, powder and granular media - are investigated in the paper aiming at the creation of the new computer model, taking into account the granular structure of materials, and the study of behaviour particular features for these materials at the dynamic load on its base. As a result the new method of the dynamics computer modelling for structural-heterogeneous media has been developed in the paper. The possibility of its application to real materials has been substantiated. The existence possibility for the new dynamic effect of the deformation of a material with the system of pores has been forecasted. The method, suggested in the paper, the investigation results of the pore collapse process at the shock-wave compactivity of powders and the new dynamic effect, forecasted in the paper, may be the base for the computer design of materials and technologies of their creation. The new method of the computer modelling developed and the special software created have been introduced into operationAvailable from VNTIC / VNTIC - Scientific & Technical Information Centre of RussiaSIGLERURussian Federatio
