Języki publikacji
Abstrakty
Rozpatrzono przestrzeń będącą sprężystym kompozytem warstwowym o strukturze periodycznej osłabioną szczeliną prostopadłą do uwarstwienia. Zagadnienie zostało rozwiązane w ramach modelu homogenizowanego z parametrami mikrolokalnymi (Woźniak (1987), Matysiak i Woźniak (1987)). Do analizy zastosowano metodę transformacji całkowych i dualnych równali całkowych. Otrzymano rozkład przemieszczeń i naprężeń oraz współczynniki intensywności naprężeń. Zbadano wpływ własności mechanicznych oraz geometrycznych kompozytu na rozkład współczynnika intensywności naprężeń.
The two-dimensional problem of crack normal to the layering is considered. The nonhomogeneous body is composed of periodically repeated two constituent laminae. The homogenized model with microlocal parameters given by Wozniak (1987). Matysiak and Wozniak (1987) is applied to find an approximate solution to the problem. The problem is reduced to a well-known dual integral equations. Numerical results, which show the influence of geometrical and mechanical properties of composite constituents on SIF distributions are presented in figures.
