Problems solved by technology

Since the development of professional software has always lagged behind the development of related theories, and the secondary development of general-purpose finite element software has high requirements for operators, the stress state of components under different working conditions is analyzed according to specific theoretical requirements. Technical requirements for comprehensive analysis and visual display often cannot get corresponding technical support in time, which brings many difficulties to the work

Abstract

A solving and visualized displaying method for a user-defined stress function belongs to the technical field of mechanical strength analysis by finite element numerical simulation. For difficulties possibly encountered when stress states of a member in different working conditions are comprehensively analyzed according to specific theoretical requirements by general finite element software, the method is characterized in that based on finite element stress analysis results of software MSC.Marc / Mentat 2005 to the member in different working conditions, stress component data of a unit integral point in each working condition is extracted, user-defined stress function data is set and calculated outside the general finite element software, and visualized display of the user-defined stress function data in a finite element model MSC.Marc / Mentat 2005 is realized in a data replacement manner. The method has the advantages and positive effects that the realization method is simple, feasible, wide in application range and capable of avoiding use limitation of professional software or secondary development.
