| Abstract | ||
| The buckling behaviors of antisymmetrically angle ply laminated composite plate under uniaxial compression have been studied using eigenvalue buckling analysis. In this research, the effects of aspect ratio, fiber orientation, number of layers and material properties on the critical loads have been studied. Finite element model is carried out using ANSYS package version 5.4,the adopted element is 3-D with 8 nodes shell 99 composite one. A comparison study is made between the present analysis and the finite element method FEM and good agreement is obtained. It is found that in design of an antisymmetric laminate; the thickness is not only the element which must be determined, to satisfy the constraints of the problem, but in addition, the number of layers in the laminate and their relative fiber orientation must also be considered. The mathematical model has been implemented in a MAT LAP | ||
