| Abstract: | 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. |
| Keywords: | singular fields interface edge finite element eigenanalysis method singular element hybrid element |
