Conclusion In this paper the high-order theory developed by of Reddy has been used to evaluate the influence of hygoothermal loading type and environnemental parameters on the behavior of the thick composite plate.The plate is under a transverse sinusoidal mechanical loading type coupled with different types of thermal and hygroscopic loading, the results shows a contributory role in the behaviour of thick composite plates, an important and direct influence of the hygrothermal loading has been observed on the longitudinal (SIG xx ) , transversal (SIG yy ) ,longitudinal tangential (SIG xy ) stresses,a very weak influence has been observed for the transverse shear stress (SIG xz , SIG yz ).
