- Abstract:
- Pre-treatment ( geometric modeling-grid-boundary conditions-material attribute definition )-analysis-post-processing are needed when the different plate sizes,solid solution, quenching temperature,thermal con-ductivity,stretching rate and other parameters are taken into consideration on the residual stress analysis. Themathematical model is set up for each set of parameters for analysis,repeating operation,the analysis efficien-cy is low. Based on MSC. Patran for secondary development platform,were based on Marc solver,make fulluse of the powerful features of the Patran command language,by making the custom menus and graphical in-terface,can submit automatically parameterized modeling, analysis, and read the result of analysis.The alu-minum alloy thick plate residual stress analysis software system is developed.The results show that the systemcalculation results are accurate,convenient and practical,and the efficiency is improved greatly. The errorlimit is 8.5 %.
