Abstract:

There arise usually the serious stress concentration around the hole in the composite plate with circular holes under the external loads. A calculation model of stress field of the composite plate with circular holes was built according to the theory of complex variable function. The complex stress function were derived by the affine transformation to describe accurately the stress field. The stress analysis of the composite plate with circular holes were performed by the model simulations, revealing the effects of the fiber orientation on the stress concentration and the Young's module in the two main directions on the holeedge stresses.
Key words：

Key words: material test and analysis, composite plate with circular holes, stress concentration, orthotropy, fiber direction, simulation
