Behviour of cross-ply laminatesd hybrid composIte plates with an inclined crack subjected to a uniform temperature rise

الملخص EN

Thermal buckling analysis of symmetric and ant symmetric cross-ply laminated hybrid fftplates with an inclined crack subjected to a uniform temperature rise are presented in Wt.

The first-order shear deformation theory in conjunction with variation energy as employed in the mathematical formulation.

The eight node Lagrangian finite element used for obtaining the thermal buckling temperatures of hybrid composite laminates.

Of crack size and lay-up sequences on the thermal buckling temperatures for 3˚c and ant symmetric plates are investigated.

The results are shown in graphical form boundary conditions.

Finally, from this paper, the following main results have from which the buckling temperature is affected the larger crack length more than crack length, together with other result that the buckling temperature of the plate for perforation angle is to increase while crack length is increasing.
