Volumetric spline parameterization for isogeometric analysis [PDF]
Computer Methods in Applied Mechanics and Engineering, 2020 Given the spline representation of the boundary of a three dimensional domain, constructing a volumetric spline parameterization of the domain (i.e., a map from a unit cube to the domain) with the given boundary is a fundamental problem in isogeometric analysis.

Isogeometric Analysis of FGM Plates
Materials Today: Proceedings, 2018 Abstract This work presents an isogeometric formulation for the geometrically nonlinear analysis of functionally graded material (FGM) plates. FGM plates are made of a mixture of two components (ceramic and metal) whose volume fractions vary smoothly along the thickness.

An isogeometric Reissner–Mindlin shell element based on mixed grid
Advances in Mechanical Engineering, 2018 We propose in this article a new isogeometric Reissner–Mindlin degenerated shell element for linear analysis. It is based on the mixed use of non-uniform rational basis spline and Lagrange basis functions in the same domain.
