| Abstract: | In this study,
an analysis of fibre reinforced, multi-layered composite plates, containing
circular holes, has been carried out. First, stress concentrations around a
circular hole are studied. A number of diagrams are drawn to show stress concentrations
around a hole, for each layer, using different material pairs with different E1/E2 ratios
(ratio of elasticity modulus of fibre direction to that of transverse
direction). The graphs are given, for various E1/E2 values, for the circumferential stress
values around the hole versus angular location of points, for two different
fibre orientation angles. Second, the failure of the laminated composite plate
is studied. For this purpose Tsai-Hill failure criterion and Hoffman failure
criterion are introduced. To determine the “first-ply failure” of a laminated
plate, these two failure criteria are employed. Finally, to show the effect of E1/E2 ratio on the
failure of plates a number of tables are given for different fibre orientation
angles. |
