ALE-based finite element modeling of needle-punching using embedded 1D yarns in a 3D preform

Needle-punching is widely used to introduce through-thickness reinforcement into fibrous preforms for composite materials. During the process, barbed needles repeatedly penetrate stacked layers and transfer fibers from the in-plane directions toward the thickness direction, progr...

Modeling Large‐Deformation Geotechnical Problems in Granular Soils: Integrating a Micromechanics‐Based Model With the Explicit Finite Element Method

ABSTRACT Large‐deformation problems in granular soils are of central importance in geotechnical engineering, as they govern the performance of foundations, retaining structures, and earthworks under extreme loading conditions. Reliable prediction of such phenomena remains challen...
