On topology optimization of large deformation contact-aided shape morphing compliant mechanisms
Prabhat Kumar, Roger A. Sauer, Anupam Saxena
A topology optimization approach for designing large deformation contact-aided shape morphing compliant mechanisms is presented. Such mechanisms can be used in varying operating co…
Contact with coupled adhesion and friction: Computational framework, applications, and new insights
Janine C. Mergel, Julien Scheibert, Roger A. Sauer
Contact involving soft materials often combines dry adhesion, sliding friction, and large deformations. At the local level, these three aspects are rarely captured simultaneously,…
An adaptive space-time phase field formulation for dynamic fracture of brittle shells based on LR NURBS
Karsten Paul, Christopher Zimmermann, Kranthi K. Mandadapu +3
We present an adaptive space-time phase field formulation for dynamic fracture of brittle shells. Their deformation is characterized by the Kirchhoff-Love thin shell theory using a…
A NURBS-based Inverse Analysis for Reconstruction of Nonlinear Deformations of Thin Shell Structures
N. Vu-Bac, T. X. Duong, T. Lahmer +4
This article presents original work combining a NURBS-based inverse analysis with both kinematic and constitutive nonlinearities to recover the applied loads and deformations of th…
A concise frictional contact formulation based on surface potentials and isogeometric discretization
Thang X. Duong, Roger A. Sauer
This work presents a concise theoretical and computational framework for the finite element formulation of frictional contact problems with arbitrarily large deformation and slidin…
Continuum contact models for coupled adhesion and friction
Janine C. Mergel, Riad Sahli, Julien Scheibert +1
We develop two new continuum contact models for coupled adhesion and friction, and discuss them in the context of existing models proposed in the literature. Our new models are abl…
