Triangle-Well and Ramp Interactions in One-Dimensional Fluids: A Fully Analytic Exact Solution
Ana M. Montero, Andrés Santos
The exact statistical-mechanical solution for the equilibrium properties, both thermodynamic and structural, of one-dimensional fluids of particles interacting via the triangle-wel…
Arbitrary Lagrangian--Eulerian finite element method for curved and deforming surfaces. I. General theory and application to fluid interfaces
Amaresh Sahu, Yannick A. D. Omar, Roger A. Sauer +1
An arbitrary Lagrangian--Eulerian (ALE) finite element method for arbitrarily curved and deforming two-dimensional materials and interfaces is presented here. An ALE theory is deve…
Theoretical analysis of screened many-body electrostatic interactions between charged polarizable particles
Eric B. Lindgren, Chaoyu Quan, Benjamin Stamm
This paper builds on two previous works, Lindgren et al. J. Comp. Phys. 371, 712-731 (2018) and Quan et al. arXiv:1807.05384 (2018), to devise a new method to solve the problem of…
The multiplicative deformation split for shells with application to growth, chemical swelling, thermoelasticity, viscoelasticity and elastoplasticity
Roger A. Sauer, Reza Ghaffari, Anurag Gupta
This work presents a general unified theory for coupled nonlinear elastic and inelastic deformations of curved thin shells. The coupling is based on a multiplicative decomposition…
Insight of the thermal conductivity of iron at Earth's core conditions from the newly developed direct methodology
Sheng-Ying Yue, Ming Hu
The electronic thermal conductivity of iron at Earth's core conditions is an extremely important physical property in geophysics field. However, the exact value of electronic therm…
A concise frictional contact formulation based on surface potentials and isogeometric discretization
Thang X. Duong, Roger A. Sauer

A finite membrane element formulation for surfactants
Farshad Roohbakhshan, Roger A. Sauer
Surfactants play an important role in various physiological and biomechanical applications. An example is the respiratory system, where pulmonary surfactants facilitate the breathi…
ChASE: Chebyshev Accelerated Subspace iteration Eigensolver for sequences of Hermitian eigenvalue problems
Jan Winkelmann, Paul Springer, Edoardo Di Napoli
Solving dense Hermitian eigenproblems arranged in a sequence with direct solvers fails to take advantage of those spectral properties which are pertinent to the entire sequence, an…
A new efficient hyperelastic finite element model for graphene and its application to carbon nanotubes and nanocones
Reza Ghaffari, Roger A. Sauer
A new hyperelastic material model is proposed for graphene-based structures, such as graphene, carbon nanotubes (CNTs) and carbon nanocones (CNC). The proposed model is based on a…
Computational synthesis of large deformation compliant mechanisms undergoing self and mutual contact
