High-energy laser shock processing for a rectangular HSLA steel plate considering solid-liquid-vapor phase change

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

“…Jiang and Dai [38] solved the three-dimensional steady heat conduction problem of a double-layer plate by using the Poisson method and the layer wise approach, where the double-layer structure including a coating layer and FGM layer, in addition, the separation of variables method and the layer wise approach were used to solve the three-dimensional transient thermal conduction problem. Taking into consideration the solid-liquid-vapor phase-change process [39] and the simply supported conditions [40] respectively, Jiang et al solved the three-dimensional transient temperature field of a high strength and low alloy rectangular steel plate under laser shock processing by the separate variable method. Considering the trajectory of the source was approximately a straight line as well as surface heat source model was regarded as a Gaussian-distribution of power density, Winczek et al [41] described a three-dimensional transient temperature field in a semi-infinite body caused by a moving laser heat source with any trajectory.…”

Investigation of the one-dimensional transient heat conduction problem of a coated high strength steel plate

“…Exploiting the first-order shear deformation plate model, Alshorbagy et al [7] investigated the uncoupled thermomechanical behavior of functionally graded plates. Considering high-energy laser shock processing, Jiang et al [8] carried out three-dimensional thermodynamic analysis of a high strength and low alloy rectangular steel plate. By a differential 3w method at room temperature, Shen et al [9] investigated the cross-plane thermal conductivities of five amorphous Si/Si 0.75 Ge 0.25 multilayer films deposited by magnetron sputtering with period thicknesses ranging from 2.5 nm to 50 nm.…”
