At ANSYS Workbench 11.0, the ANSYS Rigid Dynamics add-on module enables users to define joint connections in complex kinematic assemblies. This ability to model rigid and flexible parts in ANSYS Workbench Simulation via joints is beneficial since the rigid parts are modeled with mass and rigid links (that is, rigid contact elements), thus providing load transfer capabilities and allowing users ...

in this paper, the propagation of the waves in the laminated composite plates which is subjected to low velocity impact is investigated using the finite element method. a rigid metallic projectile with spherical nose is considered and the impact of this projectile with laminated composite is studied in this study. considering a finite element model the governing equations of the problem is disc...

The finite-element method is used to perform an accurate numerical study of the normal indentation of an elastic-plastic half-space by a rigid sphere. The effects of elasticity and strain-hardening rate of the half-space are explored, and the role of friction is assessed by analysing the limiting cases of frictionless contact and sticking friction. Indentation maps are constructed with axes of ...

Applied pressure in chemical mechanical polishing CMP is shared by the two-body pad–wafer and the three-body pad–abrasive– wafer contacts. The fraction of applied pressure transferred through the particle contacts is a significant factor as most of the material removal is due to abrasive particles trapped in the pad–wafer interface. In this work, the contact of a rough, deformable pad and a smo...

This paper describes a strategy for a robotic hand to pick up deformable 3D objects on a table. Inspired by human hand behavior, the robotic hand employs two rigid fingers to first squeeze such an object until it “feels” the object to be liftable. Such “feeling” is provided by a (virtual) liftability test that is repeatedly conducted during the squeeze. Passing of the test then triggers a lifti...

In this report we present the outcome of a study that attempted to answer the following question: for complex fluid-solid interaction problems, can the fluid be represented as a large number of rigid spheres that mutually interact via contact forces? We set out to answer this question by first describing the approach used in Chrono::FSI to analyze coupled fluid-solid interaction problems. This ...
