Temperature Distribution on Rectangular Composite Plate under Thermal Gradient Loading Environment: Experiment and Simulation

In this paper, the problem is how to calculate the dynamic mechanical and thermal properties. These properties are a function of the temperature at each conditioning load stage. This paper aims to investigate the influence of temperature distribution on a normal deflection through the plate thickness. In the numerical simulation, ANSYS software Ver. 18.2 is used. Both mechanical and thermal properties have been used as inputs in ANSYS software to simulate each point's temperature distribution on the composite plate. The purpose of this paper is to show that the temperature distribution is crucial in the phases of thermal fatigue (self-heating, thermomechanical degradation, and crack propagation). The composite laminate plate is exposed to out-off plane temperatures in which the temperature gradient is varied between (60 C° and -15 C°). The experiment setup's potential is the heating and cooling rig environment and the thermocouple connected to an analog interface card. The implication of temperature distribution is in diesel engine design based on durability and reliability. Points (1, 2, 3) have a regular heating and cooling rate (1.574 C/min or -1.574 C/min), while points (4, 5, 6) have an irregular rate of heating and cooling.
