A semi-analytical solution of 3-D transient temperature field for a uniform plate subjected to Gaussian-distribution laser heat source

One 3-D transient temperature field model for a thin uniform plate caused by moving laser heat source is described in present study. The with power density Gaussian-distribution form considered when finite-thin heated. By using the separate variable method and Newton-Cotes method, semi-analytical solution of conduction equation finite obtained. Numerical results show that effect distribution, speed as well aspect ratio have great influence on distribution field.
