橡胶类材料与刚性锥之间的大变形接触问题

Large Deformation Contact Problem between Rubber-Like Material with Rigid Cone

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进行了分析．研究揭示，奇异场由两个区构成；分别为扩张区（ＥＳ）和收缩区（ ＳＳ）．同时给出了两个区的基本方程、应力奇异性及应力随角坐标的变化曲线．

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. It is revealed that the singular field is composed of two sectors, which we call expanding sector (ES) and shrinking sector (SS). The basic equations for the two sectors are derived. The singularities of stresses in ES and SS are investigated, and the stresses are plotted against angle coordinate.
