New Applications of Mortar Methodology to Extended and Embedded Finite Element Formulations, formulated, the advantage of the mortar method is that it preserves . conditions associated with interfacial constraints, such that stability and convergence are more or less guaranteed, at least when some regularity of the solution is expected. In more recent work, interest has been shown by a num

Thermo-Mechanical Coupling in Beam-to-Beam Contact, or strains and temperature are manifested in many different ways. A detailed description of various issues related to the thermo-mechanical coupling in contact can be found in the monograph by [6]. In this paper a formulation of a beam-to-beam contact element for the coupled thermo-mechanical field

Incompatible modes are added to the remaining higher order term, all of these being expanded into a second order Taylor series. The minimization of potential energy yields a constraint

A Brick Element for Finite Deformations with Inhomogeneous Mode Enhancement,part. The enhancement is only applied to the inhomogeneous part which is treated as linear elastic, while a compressible Neo-Hooke material is used for the homogeneous part. To this end, the deformation gradient is multiplicatively split into its homogeneous and inhomogeneous part. Thus, the approac

Automatic Differentiation Based Formulation of Computational Models,ional models and the actual computer implementation can be achieved by means of extended automatic differentiation technique combined with automatic code generation. The paper presents automatic differentiation based form (ADB form) of a classical mathematical notation of solid and contact mechanics

Nonlinear Finite Element Shell Formulation Accounting for Large Strain Material Models,ll strains is presented. Within the finite element formulation the interpolation of the independent shell strains consists of two parts. The first part corresponds to the interpolation of the stress resultants. Within the second part thickness strains are incorporated, which allows direct implementa
