Abstract
It is well established that the standard FE formulation produces mesh-biased results in many situations. Additionally, in cyclic loading situations, isotropic damage models are inadequate for considering the microcrack closure-reopening (MCR) effects, making the use of orthotropic models mandatory. Recently, mixed finite elements have been re-examined by [1-2] to deal with cracking problems with enhanced accuracy using isotropic and orthotropic damage. The use of an independent approximation for...
