摘要
对于各向同性或特殊各向异性弹性楔形体,由于面内位移和面外位移不耦合,楔形体承受液体压力和体力时的应力场为经典的李维解。而对于一般各向异性弹性楔形体,通常面内位移和面外位移相互耦合。本文根据二维变形弹性体的Stroh理论,分析了液体压力和体力作用下一般各向异性弹性楔形体的应力场,并计算了复合楔形体的应力。
The in-plane displacement and the anti-plane displacement are uncoupled for an isotropic or a special anisotropic elastic wedge. Howover, they are coupled for a general anisotropic elastic wedge in general. Based on the Stroh formalism of two-dimensional deformation for elastic materials, the stress fields of the general anisotropic elastic wedges subject to liquid pressure and body force are analyzed, the stresses of composite wedges are calculated.
