Bending failure of laminated fibrous composite plates with a hole
- Naval Postgraduate School, Monterey, CA (United States). Dept. of Mechanical Engineering
This study investigates failure modes and failure strengths of laminated fibrous composite plates with stress concentration and subjected to bending loads. Graphite/epoxy composites are used for the present study. Lamina material properties, such as stiffness and strength, of the composite are determined from experiments. A series of four-point bending tests are conducted for laminated, graphite/epoxy composite plates with and without a hole to examine their failure modes and strengths. The paper compares different failure modes and strengths of various composite specimens. In addition, finite element analyses are performed to compute stress distributions around holes of the composite plates subjected to bending loads. Numerically predicted failure loads agree well with experimental results.
