摘要
本文采用编制的有限元程序求解了无限大板中含有单个具有角点的刚性夹杂在无限远处均布外载作用下夹杂角点附近的位移场,并结合Inshikawa的工作,求得了相应的应力强度因子。在此基础上,着重分析了两个刚性夹杂间的相互作用,得到了双夹杂左右角点附近的K_(Ⅰ,Ⅱ)值随夹杂间距离改变而变化的规律。
By means of finite element method (FEM), we obtain the singular stress and displacement fields around a corner point of a rigid square inclusion in infinite plate under tension. The two types of the stress intensity factors KI and KII which correspond to Mode 1 (opening Mode) and Mode 11 (in-plane shear Mode) deformation, respectively, are determined and their numerical results show good a-greement with the exact solutions by H. Ishikawa. Based on the above arguments, the interaction between two rigid square inclusions in the infinite plate under tension loading is discussed.
