Web25 mrt. 2024 · Shear Locking. Shear locking can occur in first-order, fully-integrated elements (C3D8) that are subjected to bending. This occurs when artificial shear strain develops due to an inability of the element edges to bend. As a result of this nonphysical shear strain, these elements can be too stiff when used in bending-dominant problems. WebThe second order steady state solver is used, requires LS-DYNA MPP Dev 114223 (or higher) with double precision. Basics : Weak FSI This LS-DYNA simulation shows a simple FSI coupling problem using weak/loose/explicit FSI. A rigid cylinder has a prescribed displacement in the Y direction.
