Reconstrucción de tensiones para el método de elementos finitos con mallas poligonales
TL;DR: In this paper, a tecnica de estimación del error de discretizacion for mallas de elementos finitos poligonales is presented, based on the reconstruccion de la solucion in tensiones.
Journal ArticleDOI
A MINI element over star convex polytopes
Amrita Francis,Alejandro Ortiz-Bernardin,Stéphane Bordas,Stéphane Bordas,Stéphane Bordas,Sundararajan Natarajan +5 more
TL;DR: In this paper, the authors extended the MINI element over triangles to star convex arbitrary polytopes by employing the volume averaged nodal projection (VANP) method over poly topes in combination with the strain smoothing technique.
Journal ArticleDOI
Quasi-static thermoelastic fracture: Adaptive phase-field modeling with variable-node elements
TL;DR: In this article , a hybrid adaptive phase field method discretized by using finite element method to model quasi-static fracture of thermoelastic solids and quenching is presented.
Book ChapterDOI
Modeling Fracture in Straight Fiber and Tow-Steered Fiber Laminated Composites—A Phase Field Approach
TL;DR: In this article, the role played by the orientation of the fiber, initial crack location, and the inter-fiber spacing on the fracture pattern in the composite was explored, where the fiber-matrix interface's effect on the crack path was investigated.
Journal ArticleDOI
Robust modelling of implicit interfaces by the scaled boundary finite element method
TL;DR: A robust framework based on the scaled boundary finite element method to model implicit interfaces in two-dimensional differential equations in nonhomegeneous media that can work with an efficient local mesh refinement using hierarchical background meshes is proposed.
