摘要 为了求解各向异性接合材料界面端部奇异性应力场,建立了一种新型杂交元模型。该模型的独特之处在于:基于有限元特征法得到的奇异性场数值特征解建立了一种新型界面端奇异单元。通过算例证明,新型杂交元模型能够利用较少的单元数获得较为精确的数值结果。当前模型应用范围广泛,能够用于复杂结构的界面端部场求解。 In order to solve the singular stress fields in tips of bonded dissimilar anisotropic materials, a novel hybrid element model is established. The characteristic of this model is : a new interface edge singular element model is derived based on the numerical fundamental solutions obtained from the finite element eigensolutions method. Benchmark examples show present model converges to existing solutions with fewer elements. Present model has a strong applicability, and can be used to deal with more complex interface edge problems.
