Journal ArticleDOI
Finite element modelling of orthotropic material behaviour in pneumatic membranes
TL;DR: In this paper, a generalized stored energy function is developed via a series of loading tests on a representative sample of this composite material, and the exponents in the effective law are chosen so as to fulfil basic restrictions, discussed in the body of the paper.
Journal ArticleDOI
On the computation of the macroscopic tangent for multiscale volumetric homogenization problems
İlker Temizer,Peter Wriggers +1 more
TL;DR: In this article, a condensation procedure that employs the macroscopic tangent information from the microscale finite element analysis is derived within a special framework where deformation controlled boundary conditions in micromechanical testing are enforced via the penalty method.
Journal ArticleDOI
A machine learning based plasticity model using proper orthogonal decomposition
TL;DR: In this paper, a machine learning based material modelling framework is proposed for both elasticity and plasticity, which can be trained offline to fit an observed material behaviour and then be applied in online applications.
Journal ArticleDOI
Thin shells with finite rotations formulated in biot stresses : theory and finite element formulation
TL;DR: In this paper, a bending theory for thin shells undergoing finite rotations is presented, and its associated finite element model is described, and the kinematic assumption is based on a shear elastic Reissner-Mindlin theory.
Journal ArticleDOI
NURBS- and T-spline-based isogeometric cohesive zone modeling of interface debonding
TL;DR: In this paper, the interface is discretized with generalized contact elements which account for both contact and cohesive debonding within a unified framework, which is suitable for non-matching discretizations of the interacting surfaces in presence of large deformations and large relative displacements.
