A discrete mechanics model for deformable bodies
This paper describes the theory and implementation of a discrete mechanics model for deformable bodies, incorporating behavior such as motion, collision, deformation etc. The model is fundamentally based on inter-atomic interaction, and recursively reduces resolution by approximating collections of many high-resolution elements with fewer lowerresolution elements. The model can be viewed as an ...
متن کاملMerging deformable and rigid body mechanics simulation
We present an interface between a deformable body mechanics model and a rigid body mechanics model. What is novel with our approach is that the physical representation in both the models is the same, which ensures behavioral correctness and allows great flexibility. We use a massspring representation extended with the concept of volume, and thus contact and collision. All physical interaction o...
متن کاملFluid Mechanics of Deformable Aortic Prostheses
The simultaneous replacement of a diseased aortic valve, aortic root and ascending aorta with a composite graft equipped with a prosthetic valve is a nowadays standard surgical approach, known as the Bentall procedure: the Valsalva sinuses of the aortic root are sacrificed and the coronary arteries are reconnected directly to the graft. In practice, two different composite–material prostheses a...
متن کاملA mechanics model for sheet-metal stamping using deformable dies
This paper studied the deformation mechanisms of sheet metals stamped by rigid punches and deformable dies. Emphasis was placed on the development of elastic plastic zones in the sheet workpieces, on the functions of the die parameters and on their correlations with spring-back. It was found that the reduction of spring-back was due mainly to the interface interaction offered by the dies. The p...
متن کاملJournal of Solid Mechanics Vol
The dynamic stability of a composite plate with external electrorheological (ER) damper subjected to an axial periodic load is investigated. Electrorheological fluids are a class of smart materials, which exhibit reversible changes in mechanical properties when subjected to an electric field. As a result, the dynamic behavior of the structure is changed. The ER damper is used for suppressing th...
