A thermomechanical interface element formulation for finite deformations

摘要: Interfacial layers are thermally and mechanically described in the presented approach. The combination of temperature evolution mechanical loading influences significantly deformation thermal behavior. A consistent framework is derived from principle thermodynamical laws balance equations. approach incorporated finite element analysis framework, wherein unknown temperature- displacement fields obtained, e.g. by a Newton-type solution scheme. equations linearized fully coupled interface formulation given with respect to thermomechanical residuals stiffnesses. Bonds between opening crack flanks main mechanisms delamination process. These bonds can be different nature, depending on bulk material. They constitutively terms transmission tractions heat. Numerical examples shown order demonstrate predictive capabilities element.
