چکیده انگلیسی
The hyperbolic energy model is applied in this paper for determining transient temperature variation across a unidirectional composite plate subjected to different temperature changes at the boundaries. Thermal stresses developed are then analyzed for different material properties. Governing equations are solved numerically using implicit methods. The results are presented over a wide range of variables commonly found in most composite materials. The transient thermal stresses generated inside the plate were found to fluctuate between compressive and tensile quantities, a result that was not predicted using the classical heat model. Consequently, this will lead to an earlier crack initiation and failure of the material.
