For rubber-like material half space compressed by a rigid cone, the stress singular field near the tip of the rigid cone is analyzed by large strain theory. 应用大变形理论对刚性锥压缩作用下橡胶类材料半空间锥尖附近的应力奇异场(SF)进行了分析.研究揭示,奇异场(SF)由两个区构成;
As a consequence, the viscosity of material is an important factor in the study of singular field of the crack-tip. 因此,在研究裂纹尖端的奇异场(SF)时,材料的粘性效应是一个重要的因素。
The sectorial singular field whose origin locates at the tip of the crack and radius is r 0 can be degenerated into one-dimensional linear region, which is one segment bounded by two points representing the two free crack faces. 以奇异点为原点半径为r0的扇形奇异区域,可以简化为一维线性领域,即一条以代表结合材料的两个自由表面为端点的线段。
