Abstract: In this study, it is aimed to analyze the free vibration behavior of cross-ply laminated composite rectangular thick plates with mixed finite element method based on the Gâteaux differential. Mixed finite element model has eight unknowns, displacement, bending and twisting moments, rotations and shear forces. In the free vibration analysis, laminated composite rectangular thick plates are considered for different geometrical and material parameters, lamination scheme and boundary conditions. Accuracy of the presented functional and mixed finite element formulation is shown by comparing the results of numerical examples with the ones available in the literature. The results obtained in this study are found to be in good agreement

Author(s): TAHANY W. SADAK
Abstract: Presented work discusses research results concerning the effect of the heat treatment process. Thermal fatigue which expresses repeated heating and cooling processes affect the ductility or the brittleness of the material. In this research 70 specimens of steel (1.5 mm thickness, 85 mm length, 32 mm width) are subjected to thermal fatigue at different conditions. Heating temperatures; Th = 100, 300 and 500 ° C. Number of repeated cycles; N =1 to 100. Results are evaluated then compared to each other and to that of specimens without subjected to thermal fatigue.
