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 method for solving and visually displaying a self-defined stress function belongs to the technical field of finite element numerical simulation mechanical strength analysis. The present invention aims at the difficulties that may be encountered when general-purpose finite element software performs comprehensive analysis of specific theoretical requirements on the stress state of components under different working conditions, and is characterized in that: based on MSC.Marc / Mentat 2005 software, different working conditions For the finite element stress analysis results of the lower member, by extracting the stress component data of the unit integration points under various working conditions, set and calculate and solve the custom stress function data outside the general finite element software, and realize the custom stress function data by means of data replacement. Visualization of stress function data on MSC.Marc / Mentat 2005 finite element model. The advantages and positive effects of the present invention are that the realization method is simple and easy, the application range is wide, and the use limitation of professional software or secondary development can be avoided.

Description

technical field [0001] The invention belongs to the field of finite element numerical simulation mechanical strength analysis, and in particular relates to a method for solving and visually displaying a self-defined stress function. technical background [0002] The finite element method is a numerical simulation technology that uses mathematical approximation methods to simulate real physical systems, and can analyze field quantities such as stress, strain, and displacement of components under external load conditions. MSC.Marc / Mentat 2005 is an internationally famous general-purpose finite element analysis software.
