Abstract:
The double variational adjustment on research of stress-strain behavior of construction, made of non-homogeneous plastic-rigid but also of linear elastic material is achieved. Basing on variational principles of elasticity theory and flow theory were built functionals, having extreme features. The example of calculation is given.
Keywords:
variational principles of elasticity theory; variational principles of plasticity theory; rigid plastic body; thermal mechanics; elastic plastic straining.
