摘要：
Analytical solutions to predict the perforation of fully clamped, woven E-glass/polyester panels subjected to static indentation by a blunt cylinder were derived. Three panel aspect ratios of 12.5, 25 and 50 were considered in order to show how modes of failure vary with panel flexibility. The analytical solutions for the deformation and interlaminar shear stresses compared well to finite element predictions using ABAQUS. It was found that the panel with an aspect ratio of 50 underwent large deformation and deformed in a membrane phase before fracture due to tensile necking. Failure of panels with aspect ratios of 12.5 and 25 was predicted using ply-by-ply failure analysis and the Tsai-Wu failure criterion. (C) 2004 Elsevier Ltd. All rights reserved.
