Isogeometric treatment of large deformation contact and debonding problems with T-splines: a review
Curved and Layered Structures, 2015 Within a setting where the isogeometric analysis (IGA) has been successful at bringing two different research fields together, i.e. Computer Aided Design (CAD) and numerical analysis, T-spline IGA is applied in this work to frictionless contact and mode ...

Comparison Between T-Spline Surface and NURBS Surface [PDF]
Engineering and Technology Journal, 2015 This research uses T-spline for surface modeling and compares it with NURBS modeling to get the best modeling points between the two methods. The comparison will be through surface analysis and manufacturing process.T-Splines surfaces typically have 50 ...

Multivariate Analysis-Suitable T-Splines of Arbitrary Degree
Computational Methods in Applied Mathematics, 2023 Abstract This paper defines analysis-suitable T-splines for arbitrary degree (including even and mixed degrees) and arbitrary dimension. We generalize the concept of anchor elements known from the two-dimensional setting, extend existing concepts of analysis-suitability and show their sufficiency for linearly independent T-splines.

MathematicsIsogeometric analysis (IGA) is a numerical methodology for solving differential equations by employing basis functions that preserve the exact geometry of the domain. This approach is based on a class of mathematical functions known as NURBS (Non-Uniform

Niche partitioning as a mechanism for locally high species diversity within a geographically limited genus of blastoid. [PDF]
PLoS ONE, 2018 Deltoblastus batheri and Deltoblastus delta occur concurrently in many Permian deposits from Timor. Closely related sister species living in direct proximity without alteration in feeding habit would be in direct violation of Lotka-Volterra dynamics ...

Adaptive refinement for unstructured T-splines with linear complexity
Computer Aided Geometric Design, 2022 We present an adaptive refinement algorithm for T-splines on unstructured 2D meshes. While for structured 2D meshes, one can refine elements alternatingly in horizontal and vertical direction, such an approach cannot be generalized directly to unstructured meshes, where no two unique global mesh directions can be assigned.

Transfinite Patches for Isogeometric Analysis
MathematicsThis paper extends the well-known transfinite interpolation formula, which was developed in the late 1960s by the applied mathematician William Gordon at the premises of General Motors as an extension of the pre-existing Coons interpolation formula. Here,
