Finite Element Analyses of Multi-Material Wedges and Junctions with Singular Antiplane Stress Fields

摘要

In this paper a kind of wedge-tip hybrid element based on the eigenanalyisis solutions is established and incorperated with the assumed hybrid-stress finite element model to slove the singular antiplane stress fields in tips of multi-material wedges and junctions. The new model is verified by dealing with the crack problem in an infinite body. As application, some typical multi-material wedge and junction configurations are investiged. All the caculations show that present method gives converged solution with fewer elements, and has a strong applicability.
