Abstract
The mechanical response of a uniaxially loaded graphite-epoxy plate containing a circular hole is presented. Experimental techniques of strain gages and birefringent coating are employed. Stress, strain and failure results are compared with theoretical and finite-element predictions, and with those from previously reported similar glass-epoxy and boron-epoxy plates. Catastrophic plate failure occurred at a nominal stress (gross area) of 23,850 psi, compared to a coupon ultimate strength of 61,400 psi. While the hole therefore reduces the strength of the plate by a factor of 2. 6, the ultimate strain on the boundary of the hole at fracture is greater than that for a plate without a hole.
