A new efficient ab-initio approach for calculating the bending stiffness of 2D materials
Farzad Shirazian, Roger A. Sauer
This work proposes a new efficient approach for calculating the bending stiffness of two-dimensional materials using simple atomistic tests on small periodic unit cells. The tests…
New hybrid quadrature schemes for weakly singular kernels applied to isogeometric boundary elements for 3D Stokes flow
Maximilian Harmel, Roger Andrew Sauer
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. S…
A new anisotropic bending model for nonlinear shells: Comparison with existing models and isogeometric finite element implementation
Eshwar J. Savitha, Roger A. Sauer
A new nonlinear hyperelastic bending model for shells formulated directly in surface form is presented, and compared to four prominently used bending models. Through an essential s…
An isogeometric finite element formulation for frictionless contact of Cosserat rods with unconstrained directors
Myung-Jin Choi, Sven Klinkel, Roger A. Sauer
This paper presents an isogeometric finite element formulation for nonlinear beams with impenetrability constraints, based on the kinematics of Cosserat rods with unconstrained dir…
An isogeometric finite element formulation for boundary and shell viscoelasticity based on a multiplicative surface deformation split
Karsten Paul, Roger A. Sauer
This work presents a numerical formulation to model isotropic viscoelastic material behavior for membranes and thin shells. The surface and the shell theory are formulated within a…
