Journal ArticleDOI
Isogeometric Reissner–Mindlin shell analysis with exactly calculated director vectors
TL;DR: An isogeometric Reissner-Mindlin shell derived from the continuum theory is presented and the improved accuracy yields considerable savings in computation cost for a predefined error bound.
Journal ArticleDOI
The weak substitution method – an application of the mortar method for patch coupling in NURBS‐based isogeometric analysis
TL;DR: A mortar‐type method for the coupling of non‐conforming NURBS (Non‐Uniform Rational B‐spline) surface patches to provide a simple and efficient way to couple the individual patches of complex geometrical models without altering the variational formulation.
Journal ArticleDOI
An efficient and robust rotational formulation for isogeometric Reissner–Mindlin shell elements
TL;DR: In this paper, an efficient and robust isogeometric Reissner-Mindlin shell formulation for the mechanical simulation of thin-walled structures is presented. But the authors do not consider the non-uniform rational B-splines (NURBS) surfaces in industrial design software.
Journal ArticleDOI
Dual and approximate dual basis functions for B-splines and NURBS – Comparison and application for an efficient coupling of patches with the isogeometric mortar method
TL;DR: Numerical examples show that the explicitly defined dual basis functions with minimal support severely deteriorate the global stress convergence behavior of the mechanical analysis.
Journal ArticleDOI
Treatment of Reissner–Mindlin shells with kinks without the need for drilling rotation stabilization in an isogeometric framework
Wolfgang Dornisch,Sven Klinkel +1 more
TL;DR: This work presents a framework for the computation of complex geometries containing intersections of multiple patches with Reissner-Mindlin shell elements to provide an isogeometric finite element implementation which neither requires drilling rotation stabilization, nor user interaction to quantify the number of rotational degrees of freedom for every node.
