内容記述 An elastic-plastic stress analysis was conducted for inhomogeneous fiber-reinforced plastic (FRP) containing a mode Ⅰ matrix crack by means of the finite element method. The inhomogeneous FRP was modeled as a two-dimensional laminated structure composed of elastic-perfectly plastic matrix, orthotropic elastic fiber and homogeneous FRP. The extent and the shape of the yielding zone around the crack tip for the inhomogeneous FRP were compared to those for the unreinforced matrix material. Under tha same value of the matrix stress intensity factor, KⅠm, the length of the plastic zone ahead of the crack tip, ωx/dm, for the inhomogeneous FRP was nearly equal to that for the unreinforced matrix matertial in the range of KⅠm ≤0.7 σγ (πdm) ^{1/2}, where σγ is the yield stress of the matrix material and dm is the height of the matrix phase in the inhomogeneous FRP. In the range of KⅠm >0.7 σγ (πdm)^{1/2}, ωx/dm for the inhomogeneous FRP was larger than that for the unreinforced matrix material. The plastic zone height, ωy/dm, is nearly identical between inhomogeneous FRP and unreinforced matrix material. A simple method is proposed to estimate the height and the length of the plastic zone in the inhomogeneous FRP from the elastic stress distribution in the inhomogeneous FRP.
