WebAdaptive I A plate is bended around a given radius. Adaptive mesh refinement with three refinement levels is used. The number of shell elements is increased from 14 in the starting mesh up to 128 in the end configuration. As refinement criterion total element angle change is employed. Adaptive II Web14 okt. 1997 · Adaptive 3. Several nodes on a cylinder are given initial velocities towards the center of the cylinder causing the cylinder to indent. To improve accuracy, adaptivity is defined so that the mesh of the cylinder is re-fined during the deformation. *CONTROL_ADAPTIVE Cylinder Undergoing Deformation with Adaptivity LS-DYNA …

Web14 okt. 1997 · Adaptive 1. This problem includes three tools a punch, a binder and a die and also includes a blank to be formed. The blank is deep drawn by the punch while the … WebOriginally in LS -DYNA, mesh fission/fusion associated with a predefined load path is accomplished by attaching two predefined boxes to a moving point in a fixed direction, …
Webvarying wall angle conical frustum was simulated using shell elements with different element edge lengths and adaptive mesh. Effects of these mesh parameters on plastic strain, punch force and form accuracy of deformed geometry has been studied. The necessary simulations for this study are performed using explicit finite element code LS-DYNA. WebLS-DYNA is the software of choice for the most advanced and complex stamping processes calculations. The accuracy of LS-DYNA is well documented, through international benchmarks in sheet metal forming, such as the NUMISHEET series of conferences.
WebI found that the number of adapted elements was too large when I performed a multi-stage forming analysis using adaptivity. Is there a way to avoid this problem? I generated a … WebIt depends on the initial mesh and the curvature of the tools. Usually it is necessary to have at least four to six elements in the blank to cover the 90-degree tool radii region. Four or five levels of refinement are commonly used. It is generally …
