TL;DR: In this article, a commercial finite element code with the capability of simulating large-strain frictional contact between two or more solid bodies is used to simulate the pile installation and pile loading.

TL;DR: A review of computational contact formulations within the framework of IGA can be found in this paper, where the main needs for future research emerging from the current state of the art are outlined.

TL;DR: In this paper, the numerical solution of large deflection structural problems involving finite strains, subject to contact constraints and unilateral boundary conditions, and exhibiting inelastic constitutive response is discussed.

TL;DR: In this paper, the point of contact between three-dimensional beams which undergo large motions is considered and the associated constraint conditions are formulated for a given beam discretization and associated contribution to the weak form has to be developed.

TL;DR: In this article, a concurrent two-scale and two-method approach for modeling the mechanical behavior of dry frictional non-cohesive granular materials is presented, where the material is modeled on the grain scale using a three-dimensional discrete element method and the remaining domain is considered continuous and modeled by the finite element method using an elastoplastic constitutive equation whose parameters are fit to the particle model via a homogenization scheme.
