ALE and CEL formulations of pile installation in sand
… subsequently integrated with the MMALE element formulation to simulate various pile installation problems. The accuracy of the numerical model is checked against the measurements. In case of any discrepancies, the underlying reasons are discussed. In addition, a hydro-mechanically coupled …

Modeling of diffusional creep and stress relaxation in copper grains during manufacturing of microelectronic integrated circuits
… governing equations are considered in the coupled formulation of mass flow and stress analysis. Vacancy concentration field in the grains subjected to external load is coupled to stress field through diffusional creep strains. The formulation has been implemented in the commercially …

A generalized finite element method for the simulation of non-planar three-dimensional hydraulic fracture propagation
… shale reservoirs involves modeling of three coupled processes: (i) the mechanical deformation of the rock induced by the applied fluid pressure on fracture faces; (ii) the flow of viscous fracturing fluid in the fracture; and (iii) the fracture propagation in the rock from the induced …

A Spacetime, Balance-Law Formulation of Coupled Atomistic and Continuum Dynamics for Solids
Coupled dynamic atomistic and continuum computational methods for solids have received much interest recently, because many problems are not addressed well by either model alone. In most coupled methods more emphasis has been placed on damping spurious reflections than on balancing momentum and …

Computational modeling of fiber reinforced composites melt flow in nozzle extrudate for polymer deposition additive manufacturing.
… the flow domain of interest. The one-way weakly coupled and two-way fully coupled analyses of flow and fiber orientation in the nozzle-extrudate flow domain are both implemented separately. The computed results, based on typical LAAM nozzle flow conditions, show that the non-Newtonian …

A finite element segregated method for thermo-chemical equilibrium and nonequilibrium hypersonic flows using adapted grids
… concerns the development of a loosely coupled, finite element method for the numerical simulation of 2-D hypersonic, thermo-chemical equilibrium and nonequilibrium flows, with an emphasis on resolving directional flow features, such as shocks, by an anisotropic mesh adaptation …

Optimal transport: theory, algorithms and applications
… in two applications in comparison to a pairwise coupled formulation. Firstly, we show theoretically and numerically that for regularized barycenter problems, the solutions corresponding to UMOT are less blurred. Secondly, UMOT performs better numerically in a transfer operator approach for the …
