Contact Hamiltonian mechanics [PDF]
Annals of Physics, 2017 In this work we introduce contact Hamiltonian mechanics, an extension of symplectic Hamiltonian mechanics, and show that it is a natural candidate for a geometric description of non-dissipative and dissipative systems. For this purpose we review in detail the major features of standard symplectic Hamiltonian dynamics and show that all of them can be ...

Congruent Weber-B ankle fractures do not alter tibiotalar contact mechanics [PDF]
Scientific ReportsCurrent treatment strategy for managing Weber B ankle fractures is mainly governed by mortise congruency, malleolar alignment, deltoid ligament competence and fracture stability.

Placing the transtibial centralisation stitch at the posterior horn of the medial meniscus best restores tibiofemoral contact mechanics and extrusion following medial meniscus posterior root tears: An in vitro biomechanical study using porcine knee joints [PDF]
Journal of Experimental OrthopaedicsPurpose To evaluate whether the position of the transtibial centralisation tunnel, on the background of an anatomical transtibial pull‐through root repair (ATPR), affects the tibiofemoral contact mechanics and meniscal extrusion for medial meniscus ...

Contact geometry and quantum mechanics
Physics Letters B, 2018 We present a generally covariant approach to quantum mechanics in which generalized positions, momenta and time variables are treated as coordinates on a fundamental “phase-spacetime”.

On the Geometry of Discrete Contact Mechanics [PDF]
Journal of Nonlinear Science, 2021 In this paper, we continue the construction of variational integrators adapted to contact geometry started in \cite{VBS}, in particular, we introduce a discrete Herglotz Principle and the corresponding discrete Herglotz Equations for a discrete Lagrangian in the contact setting.

Merged contact layer in adhesion mechanics [PDF]
E3S Web of Conferences, 2021 Predicting bond strength is the most common task in adhesion mechanics. To solve these problems, a contact layer model which describes the interaction of the substrate and adhesive layers, can be used.

Contact mechanics model of lung lobar sliding
Applications in Engineering Science, 2022 Lobar sliding is an often-overlooked aspect of lung mechanics that presents a potential source of variance in the lung mechanics and physiology of different subjects.
