Construction tools discrete finite element models of spatial bodies of the complex form with cracks and development of effective algorithms of the decision of problems of modelling of deformation process, fracture parameters mechanisc definition crack propagation process modelling are developed. On the basis of the developed approaches the decision of practical problems of life time definition of structure elements of gas-turbine engines Product Description popup.authors popup.nrat_date 2020-04-02 Close
