Seminar | Non-Intrusive Multiscale Structural Modeling with Standard and Generalized Finite Element Methods

Professor C. Armando Duarte, from the University of Illinois at Urbana-Champaign, in the USA, will hold a seminar on Non-Intrusive Multiscale Structural Modeling with Standard and Generalized Finite Element Methods, on April 19, at 11 a.m., in the INEGI auditorium.

In this talk, the professor will present a multiscale computational framework that couples Abaqus models and 3D Generalized FEM discretizations based on numerically-defined enrichment functions – the so-called GFEMgl. The structural-scale problem is modeled in Abaqus using a coarse mesh of 3D or shell elements suitable for capturing the macro-scale response of the structure. Fine-scale problems solved in parallel provide enrichment functions for the GFEMgl. These functions enable the GFEMgl to accurately approximate localized phenomena such as crack propagation and material damage using coarse meshes. The interactions between structural (Abaqus) and GFEMgl models are captured using the Iterative Global-Local (IGL) method.
