A meshfree method for analysis of thermo-elastic problems with moving heat sources in welding

Abstract

This manuscript presents the development and application of a meshfree procedure based on the finite pointset methods for thermo-elastic problems with moving heat sources, which are present in welding processes. The meshfree nature of this formulation gives the advantage of dealing with geometrical distortions and even fragmentations without the need of using computationally expensive remeshing approaches with a very simple implementation. A description of the implementation of this method and the solutions of some numerical examples are presented in order to show the potential of this formulation for dealing with thermoelasticity problems with moving heat sources and to introduce promising future fields of application.
