![]() ![]() In such context, the continuum is discretized with cubic T-splines, as well as with Non Uniform Rational B-Splines (NURBS) and Lagrange polynomial elements for comparison purposes, and a Gauss-point-to-surface (GPTS) formulation is combined with the penalty method to treat the contact constraints. ![]() A recently released commercial T-spline plugin for Rhino is herein used to build the analysis models adopted in this study. a linear operator which maps the Bernstein polynomial basis on Bézier elements to the global isogeometric basis. The isogeometric discretizations are here incorporated into an existing finite element framework by using Bézier extraction, i.e. Based on the concept of IGA, the smooth basis functions are adopted to describe surface geometries and approximate the numerical solutions, leading to higher accuracy in the contact integral evaluation. Computer Aided Design (CAD) and numerical analysis, T-spline IGA is applied in this work to frictionless contact and mode-I debonding problems between deformable bodies in the context of large deformations. ![]() Within a setting where the isogeometric analysis (IGA) has been successful at bringing two different research fields together, i.e. Isogeometric treatment of large deformation contact and debonding problems with T-splines: a review ![]()
