A frictional mortar contact approach for the analysis of large inelastic deformation problems

Mixed finite element formulation in large deformation frictional contact problem

This paper presents a mixed variational framework and numerical examples to treat a bidimensional friction contact problem in large deformation. Two different contact algorithms with friction are developed using the 2D finite element code PLAST2. The first contact algorithm is the classical node-on-segment, and the second one corresponds to an extension of the mortar element method to a unilate...

the use of appropriate madm model for ranking the vendors of mci equipments using fuzzy approach

abstract nowadays, the science of decision making has been paid to more attention due to the complexity of the problems of suppliers selection. as known, one of the efficient tools in economic and human resources development is the extension of communication networks in developing countries. so, the proper selection of suppliers of tc equipments is of concern very much. in this study, a ...

Inelastic Contact Deformation of Metal Coated Fibers

ÐMetal matrix composites (MMCs) can be synthesized by aligning metal coated ceramic ®bers in a shaped container and applying pressure at elevated temperatures. The high stresses created at the contacts between neighboring ®bers cause inelastic matrix ̄ow that ®lls inter®ber voids, reduces inter®ber separations and results in composite densi®cation. The rate of densi®cation depends on the contac...
