Optimization and analysis of stress concentration in composite laminates with different cutouts
摘要
Abstract
Based on the anisotropic elastic theory and the conformal mapping,parameters of the different shapes are discussed in one mapping function.The maximum stresses of composite laminates with circular hole,triangular hole and square hole under uniaxial tensile load are obtained.The stress concentration fac-tors with different curvature are also investigated.The results show that the stress concentration factors are very different between the three holes.In the most cases,the stress concentration factor of circular hole is minimum,but in a certain range the stress concentration factor of triangular hole is smaller than it.Finally an optimization of cutout-shape which makes the maximum stress minimized is obtained and such cutout-shape can be applied in engineering structures.关键词
