Mutual Influence of Geometric Parameters and Mechanical Properties on Thermal Stresses in Composite Laminated Plates with Rectangular Holes

In this research, the mutual influence of mechanical properties and geometric parameters on thermal stress distribution in symmetric composite plates with a quasi-rectangular hole subjected to uniform heat flux is examined analytically using complex variable technique. The analytical solution obtained based thermo-elastic theory Lekhnitskii’s method. Furthermore, by employing suitable mapping function, laminates containing circular extended hole. effect important including stacking sequence laminates, angular position, bluntness, aspect ratio angle [45/−45]s for materials are relation distribution. insulated state Neumann boundary conditions at edge taken into account. It found out that rotation angles play key roles obtaining optimum around present method can well investigate interaction effective multilayer composites under flux.
