ABAQUS material batch creation method

Abstract

The invention provides an ABAQUS material batch creation method. The ABAQUS material batch creation method comprises the following steps: inputting parameter information of materials needing to be created into the same document; reading the parameter information of the material from the document into a computer memory by adopting a Python language; judging whether the read material names are repeated or not through the Python language, and if the repeated material names exist, popping up prompt information; generating an ABAUQUS script file according to the read parameter information of the material; automatically storing the generated ABAUQUS script file in a set position; and enabling the ABAQUS CAE software to read an ABAUQUS script file, and creating materials needed by a model. According to the method provided by the invention, all the materials required by the established model can be established at one time, a user can conveniently carry out self-defined setting on each parameter of the established materials, the operation is convenient and fast, the learning cost is low, the operation efficiency is high, the efficiency of ABAQUS finite element numerical modeling is greatly improved, and the experience degree of modeling analysts is improved.

Description

technical field [0001] The invention relates to the field of finite element modeling analysis, in particular to an ABAQUS material batch creation method. Background technique [0002] With the development of computing technology and the continuous improvement of the requirements for engineering design and construction, numerical analysis and calculation have been paid more and more attention by scientific researchers, designers and engineering technicians, and the application of numerical analysis has become more and more extensive. The most commonly used and most effective method for numerical calculation analysis is the finite element method. As a large-scale general-purpose finite element analysis software, ABAQUS software has a rich material model library, powerful nonlinear calculation and processing capabilities, and a friendly human-computer interaction interface. The field of meta-modeling analysis. [0003] ABAQUS modeling analysis steps generally include: creatin...

AI Technical Summary

Problems solved by technology

Among them, the operation of creating material and cross-section properties is relatively cumbersome, and various parameters of different materials need to be set and input separately. When the model requires many types of materials, it is not only time-consuming, but also prone to errors. Often after the input of material parameters is completed, Need to check again

In addition, when different numerical models need to use the same material, it is still necessary to repeatedly input material parameters, which greatly reduces the user's modeling and analysis experience
