Two- and Three-Dimensional Transient Thermoelastic Analysis by the MLPG Method

open access: yesComputer Modeling in Engineering & Sciences, 2009
The meshless local Petrov-Galerkin (MLPG) method for transient linear thermoelastic analysis is presented. Orthotropic material properties are considered here. In uncoupled thermoelasticity, the temperature field is not influenced by displacements. Therefore, in the first step, the heat conduction equation is solved for the temperature distribution in ...
