Fractal and Fractional, 2021 This study investigates the predictions of the real contact area for perfectly elastic rough surfaces using a boundary element method (BEM). Sample surface measurements were used in the BEM to predict the real contact area as a function of load.

Asynchronous contact mechanics [PDF]
ACM Transactions on Graphics, 2009 We develop a method for reliable simulation of elastica in complex contact scenarios. Our focus is on firmly establishing three parameter-independent guarantees: that simulations of well-posed problems (a) have no interpenetrations, (b) obey causality, momentum- and energy-conservation laws, and (c) complete in finite time.

FFT-Based Methods for Computational Contact Mechanics
Frontiers in Mechanical Engineering, 2020 Computational contact mechanics seeks for numerical solutions to contact area, pressure, deformation, and stresses, as well as flash temperature, in response to the interaction of two bodies.

From Geometry to Coherent Dissipative Dynamics in Quantum Mechanics
Quantum Reports, 2021 Starting from the geometric description of quantum systems, we propose a novel approach to time-independent dissipative quantum processes according to which energy is dissipated but the coherence of the states is preserved.

The Painlevé paradox in contact mechanics [PDF]
IMA Journal of Applied Mathematics, 2016 The 120-year old so-called Painleve paradox involves the loss of determinism in models of planar rigid bodies in point contact with a rigid surface, subject to Coulomb-like dry friction. The phenomenon occurs due to coupling between normal and rotational degrees-of-freedom such that the effective normal force becomes attractive rather than repulsive ...

Advanced Numerical Methods in Computational Solid Mechanics
Mathematics, 2023 Efficient numerical solving of nonlinear solid mechanics problems is still a challenging issue which concerns various fields: nonlinear behavior, micromechanics, contact mechanics, damage, crack propagation, rupture, etc [...]

SN Applied Sciences, 2021 In grinding processes, heat is generated by the contact of the grains with the workpiece. In order to reduce damages on the workpiece and the grinding tool, cutting fluids are necessary for most grinding processes.

Contact Hamiltonian Description of 1D Frictional Systems
Communications in Advanced Mathematical Sciences, 2021 In this paper, we consider contact Hamiltonian description of 1D frictional dynamics with no conserved force. Friction forces that are monomials of velocity, and sum of two monomials are considered.
