A dual reciprocity method multi-domain (DRM-MD) approach for modeling laser–material interaction with axial symmetry was developed. The proposed approach is based on the fundamental solution for the Laplace equation in 2D and is much simpler for implementation than the dual reciprocity boundary element method (DRBEM) based on the fundamental solution for axisymmetric problems incorporating elliptic integrals. The thermal model of laser–material interaction was applied for the cases of mono as well as
multi-layer structures. Different aspects of interaction up to the melting point of considered materials are presented. The effect of temperature dependence of the absorption coefficients on the process of laser heating was considered. Numerical results for spatial as well as temporal temperature distribution inside the material bulk are presented and compared to analytical solutions.
