摘要:
板内有腰圆形孔口的情形在工程结构中经常会遇到。本文用的方法研究了单向拉伸和纯剪切下,无限板内腰圆形孔口的应力分布问题。得出了有限级数形式表达的复应力函数。对于有限尺寸板内开孔的情形,文中用有限单元法来分析腰圆形孔口的应力分布和应力集中。在小开孔时,有限板内孔口的应力分布和无限板内的情况非常接近。证明了解析解和有限五分析的一致性。文中还讨论了翼缘和环形加劲对应力集中的影响。
Abstract:
Ovaloid openings in plates are often encountered in engineering structures. The stress distribution around an ovaloid opening in infinite plates under uniaxial tension and pure shear are investigated by the method of Muskhelishvili. The complex stress functions are obtained in the form of a finite series. For the plates with finite dimensions, the finite element method is used to obtain the stress distribution and stress concentration around the ovaloid opening. In the case of small opening, the stress distribution and stress concentration in finite plates are in good agreement with those in infinite plates and this result indicates the identity of the analytical method and the finite element approach. The influences of the flange and ring-type reinforcing on the stress concentration are also discussed in this paper.
