| Abstract | ||
| A nonlinear finite element model for geometrically large amplitude free vibration analysis of composite laminated plate using high order shear deformation theory used in this work. The aim of the study is to analyze the effect of the stationary crack and hole on the free vibration of composite plate those in which the singularity due to presences of crack is modeled, so that stress field at the tip of the crack is properly represented. The results are computed for different crack, hole size, material orthotropy and different boundary condition. Finally the discrepancy of the results was 29.8249% when considered the severe nonlinearity. | ||
