Abstract
The concept of inherent strain is closely related to those of inherent stress, inherent deformation and inherent force. Since the inherent strain is transformed into the deformation when the restraint is small and it is transformed into the stress when the restraint is strong, the framework of FE code for welding simulation can be naturally and conveniently constructed by combining these concepts. The idea how they are integrated in the FE code is presented in this paper.
