The evaluation of thermal stresses in thermoplastic laminated composites with different square holes

Abstract

In this study, a thermal stress analysis was evaluated on symmetric angle-ply laminated thermoplastic composite plates that were having different square hole dimensions. The temperature loading was selected uniformly. Besides, it was applied with various values that were chosen as 50, 60, 70, 80, 90, 100°C, because of the fact that the effect of increasing uniform temperature on thermal stresses was examined. The width plate-to-the width square hole, a/b, ratios were changed as 2, and 4. Thermoplastic laminated composite plates were assumed to be simple supported. Laminated plates were composed of four orthotropic layers oriented with angle-ply in symmetric manner. The solution was carried out by using ANSYS finite element program. The results were showed in figures depending on applied temperatures, orientations and dimensions of square hole. © Association for Scientific Research.
