摘要: 本文讨论了由纤维和树脂-损伤应变软化材料组成的层合板在面内受压时的压缩分叉。用有限变开理论和半解析有限元法建立了相应的分叉方程,并进行数值模拟。计算结果表明,分叉将在损伤材料的应变软化阶段发生,为剪切带形分叉,损伤材料骨有剪应变集中,而且在纤维和树脂的界面附近有较大的剪应变突变等现象。

Abstract: The compressive bifurcation of a laminated plate composed of fibers and matrix under uniaxial compression,which is assumd to be a damage strain softening material,is investigated:Using the finite deformation theory and semi-analytical finite element method,the bifurcation equations are established,and then a numerical simulation is evaluated. The results show that the bifurcation occurs during a strain softening of the damage materials,and this bifurcation is a one of shearing band. In a damaged material the shear strain is concentrated and the shear strain jumping appears in the neighbourhood of an interface between the fibers and matrix.
