The frictional contact problem of a rigid punch sliding over thermoelectric materials
, 2020 A theoretical frictional contact model of thermoelectric materials with nonlinear thermoelectric coupling loaded by a sliding punch is considered in which the punch is also assumed to be an electrical and thermal conductor.

Surface effect on the contact problem of a piezoelectric half-plane
, 2020 Based on the theory of the surface piezoelectricity, the two-dimensional frictionless contact problem of the piezoelectric half-plane under rigid flat and cylindrical punches is investigated in this paper. The Fourier integral transform method is adopted

The contact geometry of the restricted 3-body problem [PDF]
, 2010 We show that the planar circular restricted three body problem is of restricted contact type for all energies below the first critical value (action of the first Lagrange point) and for energies slightly above it.

The Hertz contact problem in couple-stress elasticity
International Journal of Solids and Structures, 2019 The classical three-dimensional Hertz contact problem is re-examined in the present work within the context of couple-stress elasticity. This theory introduces characteristic material length scales that emerge from the underlying microstructure and has ...

Controlling sliding droplets with optimal contact angle distributions and a phase field model [PDF]
, 2019 We consider the optimal control of a droplet on a solid by means of the static contact angle between the contact line and the solid. The droplet is described by a thermodynamically consistent phase field model from [Abels et al., Math. Mod. Meth.

Multidimensional Contact Problems in Thermoelasticity [PDF]
SIAM Journal on Applied Mathematics, 1998 Summary: We consider dynamic and quasi-static thermoelastic contact problems in \({\mathbb R}^n\) modeling the evolution of temperature and displacement in an elastic body that may come into contact with a rigid foundation. The existence of solutions to these dynamic and quasi-static nonlinear problems and the exponential stability of the solutions are

Tykhonov triples and convergence results for hemivariational inequalities
Nonlinear Analysis, 2021 Consider an abstract Problem P in a metric space (X; d) assumed to have a unique solution u. The aim of this paper is to compare two convergence results u'n → u and u''n → u, both in X, and to construct a relevant example of convergence result un → u ...

Global Planning for Contact-Rich Manipulation via Local Smoothing of Quasi-Dynamic Contact Models [PDF]
IEEE Transactions on robotics, 2022 The empirical success of reinforcement learning (RL) in contact-rich manipulation leaves much to be understood from a model-based perspective, where the key difficulties are often attributed to 1) the explosion of contact modes, 2) stiff, nonsmooth ...

OPTIMIZATION PROBLEMS FOR A THERMOELASTIC FRICTIONAL CONTACT PROBLEM
Mathematical Modelling and Analysis, 2021 In the present paper, we analyze and study the control of a static thermoelastic contact problem. We consider a model which describes a frictional contact problem between a thermoelastic body and a deformable heat conductor obstacle. We derive a variational formulation of the model which is in the form of a coupled system of the quasi-variational ...
