Keywords:
FEM, Skew Laminate, Cutout, Interlaminar stressesAbstract
The behavior of a cross-ply laminated composite skew plate with elliptical hole subjected to temperature loading has been investigated in the present analysis. A finite element method, which works on the basis of three-dimensional theory of elasticity, is employed to evaluate the transverse deflection, in-plane stresses and interlaminar stresses. The results obtained by varying the skew angle, size of the cutout and the effect of elliptical cutout orientation are discussed. The magnitudes of the in-plane stresses for temperature loading are observed to be less at higher skew angles and for larger size of the cutout. There is no significant Variation of the transverse deflection. It is also observed that the configuration 3 of the ellipse (Major axis of the ellipse Collinear with the longer diagonal of the skew plate) is found to be better with respect to the major stresses point of view. The solutions of skew structures considered in the present analysis will be useful for the construction of safe and efficient structures like skew bridges and swept wings of aircraft structures.
