Comparison of the Cosserat Continuum Approach with Finite Element Interface Models in a Simulation of Layered Materials

This paper compares the formulation of the nite element Cosserat smeared approach with the combined nite element-explicit interface element approach, when both applied to the analysis of layered continua. The fundamental equations of both formulations are presented. Also, using three examples, the nature and accuracy of the displacement field predicted by both techniques are investigated and discussed.
