Thermal Stress Analysis for Local Heating Variable Cross-section Roll Forming

摘要：

　　This paper makes thermal stress analysis for local heating variable cross-section roll forming with ABAQUS finite element software.On the basis of traditional cold roll forming,local heating variable cross-section roll forming uses laser device to heat the sheet partly and employs ABAQUS to do thermal-mechanical coupling finite element analysis.This paper,adopting sequence thermal-mechanical coupling method,obtains the temperature field with heat transfer analysis step firstly,and then regards the obtained temperature field as known condition and employs static implicit algorithm to do thermal stress analysis,then the stress-strain field is obtained,which will be helpful in forecasting the stress-stain law of the local heating variable cross-section roll forming.
