Isogeometric Multiscale Modeling with Galerkin and Collocation Methods

In this work we employ isogeometric analysis (IGA) in the field of computational homogenization. We present the nonlinear governing equations for the elasticity problem with finite deformations discretized with both IGA Galerkin and collocation methods in a nested multiscale problem and then explore the accuracy and computational performance of the proposed frameworks both in microscale and multiscale problems.
