In recent years, the mortar method has proven to be an effective spatial discretization strategy for large deformation contact problems, particularly when such problems feature deformable-to-deformable contact. The mortar approach has been shown to g

In this work, we present a strong form meshfree collocation method for frictional contact problems. Frictional contact constraints are included in the strong form force balance equation as part of Neumann boundary conditions. The equation is then dir

The past 10–15 years have seen important extensions of the mortar method, a technique for joining dissimilar grids popularized by the domain decomposition community, to the more general problem of contact and impact interactions in finite element a

A new technique for treating the mechanical interactions of overlapping finite element meshes is proposed. Numerous names have been applied to related approaches, here we refer to such techniques as embedded mesh methods. Such methods are useful for

An Enhanced Energy Conserving Algorithm (EECA) formulation for time integration of frictionless contact-impact problems is presented. In it the energy, linear and angular momentum are conserved for every contact using an enhanced Penalty method. Prev

Computational treatment of immersed rigid bodies, especially in the presence of free surfaces and/or breaking waves, poses several modeling challenges. A motivating example where these systems are of interest is found in offshore wave energy harvesti

In this paper, a new numerical approach, based on mortar discretization of interface fields, is proposed to solve lubricated contact problems between deformable solid bodies. The Reynolds approximation to the thin film fluid equations is used to desc

SUMMARY Enriched finite element approaches such as the extended finite element method provide a framework for constructing approximations to solutions of non-smooth problems. Internal features, such as boundaries, are represented in such methods by u

This paper describes a new extension of mortar based, segment-to-segment algorithms for large deformation contact analysis, permitting their use when quadratic interpolations are used in the underlying finite element method. The work builds upon resu
