| 摘 要： | 论文对半平面双材料角受集中力问题的界面应力场作了深入的探究,特别着重于双材料角端点附近的界面应力的奇异性分布规律.论文通过对界面应力的严格解和渐近解16]的比较,发现在双材料角界面端点邻近,严格解和渐近解的差是一个向端点衰减的微幅震荡分布的应力.这个向端点衰减的微幅震荡应力的起始点,称为转换点.自界面端点到转换点,严...

| Abstract: | The distribution of interfacial stresses in bimaterial corners of edge-bonded quarter-planes is investigated with a particular attention to the distribution of interfacial stresses in the vicinity of the interface tip of bimaterial corners.It is found that,closely near the interface tip,the difference between the rigorous solution and the asymptotic solution of edge-bonded quarter-planes is an oscillation stress with tiny amplitude,and it quickly attenuates towards the tip.The starting position of the dampi... |
