A chemo-mechano-thermodynamical contact theory for adhesion, friction and (de)bonding reactions
Roger A. Sauer, Thang X. Duong, Kranthi K. Mandadapu
This work presents a self-contained continuum formulation for coupled chemical, mechanical and thermal contact interactions. The formulation is very general and hence admits arbitr…
An isogeometric finite element formulation for geometrically exact Timoshenko beams with extensible directors
Myung-Jin Choi, Roger A. Sauer, Sven Klinkel
An isogeometric finite element formulation for geometrically and materially nonlinear Timoshenko beams is presented, which incorporates in-plane deformation of the cross-section de…
A Bayesian regularization-backpropagation neural network model for peeling computations
Saipraneeth Gouravaraju, Jyotindra Narayan, Roger A. Sauer +1
Bayesian regularization-backpropagation neural network (BR-BPNN) model is employed to predict some aspects of the gecko spatula peeling viz. the variation of the maximum normal and…
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…
On the presence of a critical detachment angle in gecko spatula peeling -- A numerical investigation using an adhesive friction model
Saipraneeth Gouravaraju, Roger A. Sauer, Sachin Singh Gautam
A continuum-based computational contact model is employed to study coupled adhesion and friction in gecko spatulae. Nonlinear finite element analysis is carried out to simulate spa…
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,…
Isogeometric continuity constraints for multi-patch shells governed by fourth-order deformation and phase field models
Karsten Paul, Christopher Zimmermann, Thang X. Duong +1
This work presents numerical techniques to enforce continuity constraints on multi-patch surfaces for three distinct problem classes. The first involves structural analysis of thin…
