Abstract

This paper analyses the progressive failure of a variable-stiffness composite structure (VSCS). The composite structure is simulated by means of a design method developed earlier. The design method allows curvilinear fibers to be adapted to various geometric discontinuities (holes, notches, etc.) or non-uniform loading. The fiber orientation and fiber volume fraction are heterogeneous in the VSCS. To model progressive failure, a material property degradation method (MPDM) is used. The properties of the composite structure are locally changed due to the nonuniformity in the fiber volume fraction, and the change of the properties is taken into account in the MPDM. A rectangular plate with a hole under tensile loading is modeled, and it is shown that use of the VSCS is more effective than the use of a composite structure with rectilinear reinforcement (orthotropic material) under identical conditions.
