الملخص

 This study deals with thermal cyclic loading phenomena of plates which were fabricated from


 


composite materials (woven roving fiber glass + polyester) were exposed to (75 C°) temperature


 


gradient thermal shock for ten times in different stage of conditioning times due to the effect of thermal


 


fatigue using the method of Levy solution and compared these results with both results from


 


experimental published work and (ANSYS Ver. 9) program. A composite laminate plate with fiber


 


volume fraction (υf =25.076%) is selected in this study and applying the combined loadings like


 


bending moment (Mo), and in-plane force (Nxx) beside the effect of thermal fatigue. It involves multi


 


theoretical and finite element fields; but the theoretical one contains the derived equation of stresses


 


distribution and evaluating the normal deflection of a middle point for dynamic analysis applying


 


different boundary conditions for heating and cooling. The main present numerical results for a


 


composite plate with (80%) fiber volume fraction claim that the relative reduction in normal deflection


 


and dynamic load factor are (78.593%) and (9.421%) during cooling to (-15 respectively.
