The stresses in the fiber and matrix phases and along the fiber–matrix interface are calculated. When the laminated composite structure is subjected to combined thermal and mechanical loads, the macrostrains are …

Composite plates are one of the most important structures in engineering applications. These structures are often used in thermal environments where they can generate thermal stresses and affect the vibrational characteristics of structure [1-5]. Although skew plates play an important role in engineering structures, only few research works have been devoted to analyzing the free vibration of

Thermal buckling analysis of ceramic-metal functionally graded plates Ashraf M. Zenkour1,2*, used to determine thermal buckling loads of composite plates. The classical plate theory [24], which is based on Kirchhoff’s hypothesis, overestimates the thermal buck-ling load when applied to even moderately thick plates. This is particularly true for composite plates in which transverse shear
