Th e complex plasto-elastic deformation model of mechanical multiple freedom degree system
In order to study the plastic resource of the structure, the plasto-elastic single freedom degree model described by the Prandtl diagram is widely used. In the paper this approach is generalized to multiple freedom degree system. Th is model allows investigating the plastic resource of structures under conditions of complex, disproportionate by individual components, deformation. Th is greatly increases the accuracy of the calculations carried out. Implementation of calculations according to the proposed macro-model is easier than carrying out the detailed dynamic plasto-elastic calculations using the existing soft ware systems such as ANSYS.
