摘要
本文研究更复杂的受载情形 ,即有压缩载荷 ,又有弯曲载荷作用下的局部屈曲问题 ,用基于一阶剪切层板理论的几何非线性有限元法分析了受压 -弯载荷作用下含穿透脱层层板的屈曲临界载荷。
Local buckling of delaminated laminates subjeceted to compressive loads creates delamination buckling.This often causes delamination growth and leads the structure to failure.This paper deals with more complicated problems that there are compressive loads as well as bending loads.In this paper one-dimensional modelling of delaminated laminates is developed based on the first order shear deformable plate theory The critical buckling loads of laminates embedding one-dimensional delamination under compress-bend loads are calculated using a geometrically nonlinear one-dimensional finite element analysis. Critical loads curves are given under different ratios-bend of compress loads.
