Uma estratégia adaptativa para problemas de contato em elasticidade
ln this work an adaptive remeshing scheme in used to solve contact problems with Coulomb friction. An existing 2D mesh generator based on a frontal technique is used for the construction of the initial mesh of triangular elements. The contact problem is then solved using a sequence of sub-problems …

Adaptive finite element simulation of fracture: from plastic deformation to crack propagation
… investigate topological and physical aspects of adaptive remeshing for two types of structural systems: quasi-brittle and ductile. For ductile systems, we are interested in modeling the large deformations that occur before rupture of the material. The deformations can be so large that element …
