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 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.
