Abstract
Based on the method of separation of variables and equivalent temperature method, three-dimensional transient temperature field for a fiber metal laminated (FML) plate with a coating layer (total structure is named as a CFML structure) during laser surface treatment process is firstly obtained. Subsequently, the three-dimensional transient thermodynamic governing equations for the CFML structure under such laser work condition are solved by applying the finite difference method and Newmark method in space domain and time domain, respectively. The aim of this research is to give the analytical solution of three-dimensional transient temperature field for CFML structure under laser surface treatment technology, understand the influence of number of fiber species, laser moving velocity, number of FML layers and selected coating layer’s heat conduction coefficient on the deflection, normal stress, shear stress and vibration frequency of the CFML structure. Besides, it could guide engineers designing the CFML structure to adapt to hostile laser surface treatment environment.
