Popis: | The conditions of constructing effective numerical algorithms for calculating stresses and plastic deformations for a number of widely used plasticity equations are analyzed. An iteration-free method is used for taking into account temperature changes in the moduli of elasticity when formulating the boundary-value problem of thermoplasticity in increments. A method is proposed for eliminating the shortcomings of the power approximation of stress-strain diagrams of materials, which enables preserving the available databank of approximation constants. |
