Formulations of the deformable foundation contact problems
Journal of Civil Engineering and Management, 2002 Up to now in many works a construction on elastic foundation was modelled by the Winkler's hypothesis. In this paper the flexible plate-foundation system is investigated as an interaction of separate elastic bodies, which lie on the contact surface. Such

Contact Problems in Porous Media
Computational Methods in Applied MathematicsAbstract The Biot problem of poroelasticity is extended by Signorini contact conditions. The resulting Biot contact problem is formulated and analyzed as a two field variational inequality problem of a perturbed saddle point structure. We present an a priori error analysis for a general as well as for an hp-FE discretization including ...

Numerical analysis of a contact problem with wear [PDF]
Computers & Mathematics with Applications, 2020 This paper represents a sequel to the previous one, where numerical solution of a quasistatic contact problem is considered for an elastic body in frictional contact with a moving foundation. The model takes into account wear of the contact surface of the body caused by the friction. Some preliminary error analysis for a fully discrete approximation of

Tykhonov well-posedness of fixed point problems in contact mechanics
Fixed Point Theory and Algorithms for Sciences and Engineering, 2022 We consider a fixed point problem S u = u $\mathcal {S}u=u$ where S : C ( R + ; X ) → C ( R + ; X ) ${\mathcal {S}:C(\mathbb{R}_{+};X)\to C(\mathbb{R}_{+};X)}$ is an almost history-dependent operator.

On Nitsche's Method for Elastic Contact Problems [PDF]
SIAM Journal on Scientific Computing, 2020 We show quasi-optimality and a posteriori error estimates for the frictionless contact problem between two elastic bodies with a zero-gap function. The analysis is based on interpreting Nitsche's method as a stabilised finite element method for which the error estimates can be obtained with minimal regularity assumptions and without the saturation ...

NUMERICAL AND ANALYTICAL PROBLEMS OF FATIGUE STRENGTH IN ROLLING BEARINGS [PDF]
Scientific Journal of Silesian University of Technology. Series Transport, 2014 The aim of the work is to create an algorithm of fatigue life prediction for typical rolling bearings. The proposed approach makes use of various, well established hypothesis for multiaxial fatigue applied in engineering calculations. In the first part
