Numerical-and-aralytical methods of deformation calculation and evaluation of structural member strength in mechanical engineering

Abstract

The paper deals with various approaches to calculating deformation fields in plastic deformation localization areas (deformation concentrators), including those based on rigid plastic analysis. Algorithms of incorporating rigid plastic super elements into familiar program packages likeMSC,ANSYS are proposed. Limiting values of deformation tensor field are calculated. An approach to evaluating structural member strength is proposed.
