EXPERIMENTAL AND THEORETICAL STRESS ANALYSIS INVESTIGATION FOR COMPOSITE PLATE UNDER THERMAL LOAD

Emad Q. Hussein, Sara J. Alasadi

Abstract


A paper focuses on the investigation of the stress-strain for E-glass fiber /polyester composite plates subjected to the uniform temperature at various factors, such as fiber volume fraction and fiber orientation. To study the stress analysis of composite plate two methods are used: The First method is an experimental test by applying a uniform temperature on the composite plate inside the furnace and a measure the deformation of the plate by using dial gage. The second method based on a finite element solution using ANSYS (ver. 15) program. The results presented here that, the maximum strain in longitudinal direction occurs at a ply angle (90º), whereas the minimum value at a ply angle (0º). However, the maximum strain in transverse direction occurs at a ply angle (0º) whereas the minimum value at a ply angle (90º). In general, the magnitude of thermal strain increases with increasing temperature difference (∆T) and decreases with increasing the fiber volume fraction (
