Modified Strip Model for Analyzing the Line Heating Method-Part 2: Thermo-Elastic-Plastic Plates

A modified strip method is developed for analyzing the process of plate forming by the line heating method. The idea has been presented in Part 1 for analyzing elastic plates, and it is extended here to simulate approximately the transient thermo-elastic-plastic plate bending. Two cases are discussed. First, the case of uncoupled thermo-elastic-plastic plate is studied illustrating the use of a modified strip model. Second, generalized coupled governing equations for the thermo-elastic-plastic modified strip are derived and discussed. The results, with the use of a regular strip model, indicate a qualitative error in comparison with the use of a plate model, whereas with the use of a modified strip model a qualitative agreement is reached. Finally, suggestions for future research work are given.
