Isogeometric analysis (IGA) represents a recently developed technology in computational
mechanics that offers the possibility of integrating methods for analysis and Computer Aided …

We review the treatment of trimmed geometries in the context of design, data exchange, and
computational simulation. Such models are omnipresent in current engineering modeling …

In the past two decades, meshfree methods have emerged into a new class of computational
methods with considerable success. In addition, a significant amount of progress has been …

Sequences of matrices with increasing size naturally arise in several contexts and especially
in the discretization of continuous problems, such as integral and differential equations. The …

We couple collocated isogeometric boundary element methods and unstructured analysis-
suitable T-spline surfaces for linear elastostatic problems. We extend the definition of …

The concept of isogeometric analysis, where functions that are used to describe geometry in
CAD software are used to approximate the unknown fields in numerical simulations, has …

We compare isogeometric collocation with isogeometric Galerkin and standard C 0 finite
element methods with respect to the cost of forming the matrix and residual vector, the cost …

Conventional finite shell element formulations use rotational degrees of freedom to describe
the motion of the fiber in the Reissner–Mindlin shear deformable shell theory, resulting in an …

Since most approximation functions in meshfree methods are rational functions which do not
possess the Kronecker delta property, how to achieve exact integration and accurately …

We study NURBS-based isogeometric analysis of contact problems and compare with
standard C0-continuous Lagrange finite elements. A knot-to-surface (KTS) algorithm is …
