Report

New hybrid quadrature schemes for weakly singular kernels applied to isogeometric boundary elements for 3D Stokes flow

Autor: Harmel, Maximilian, Sauer, Roger Andrew

Publikováno v: Engineering Analysis with Boundary Elements, 2023, 153:172-200

This work proposes four novel hybrid quadrature schemes for the efficient and accurate evaluation of weakly singular boundary integrals (1/r kernel) on arbitrary smooth surfaces. Such integrals appear in boundary element analysis for several partial

Report

A general isogeometric finite element formulation for rotation-free shells with in-plane bending of embedded fibers

Autor: Duong, Thang Xuan, Itskov, Mikhail, Sauer, Roger Andrew

This paper presents a general, nonlinear isogeometric finite element formulation for rotation-free shells with embedded fibers that captures anisotropy in stretching, shearing, twisting and bending -- both in-plane and out-of-plane. These capabilitie

Report

A general theory for anisotropic Kirchhoff-Love shells with in-plane bending of embedded fibers

Autor: Duong, Thang Xuan, Khiêm, Vu Ngoc, Itskov, Mikhail, Sauer, Roger Andrew

This work presents a generalized Kirchhoff-Love shell theory that can explicitly capture fiber-induced anisotropy not only in stretching and out-of-plane bending, but also in in-plane bending. This setup is particularly suitable for heterogeneous and

An isogeometric finite element formulation for frictionless contact of Cosserat rods with unconstrained directors

Autor: Choi, Myung-Jin, Klinkel, Sven, Sauer, Roger Andrew

Publikováno v: Computational mechanics 70(6), 1107-1144 (2022). doi:10.1007/s00466-022-02223-5

This paper presents an isogeometric finite element formulation for nonlinear beams with impenetrability constraints, based on the kinematics of Cosserat rods with unconstrained directors. The beam cross-sectional deformation is represented by directo
