In part I of this work, we study adhesionless contact of a long rectangular elastic membrane with a rigid substrate. Our model is based on finite strain theory and is valid for arbitrarily large deformations. Both frictionless and no-slip contact conditions are considered. Exact closed form solutions are obtained for frictionless contact. For small contact, the differences between these two con...

this paper concerns the design and analysis, of a ball type continuously variable transmission, (b-cvt). this b-cvt has a simple kinematic structure, and same as a toroidal cvt, transmits power by friction on the contact points between input and output discs, that are connected to each other by balls. after, a brief introduction of our b-cvt structure, the performance and traction efficiency of...

Although cutting flow peanut-picking is the main peanut harvesting method, it has problems of a large harvest loss and high damage rate shells. The analysis impact-friction contact characteristics during fruit picking crucial to illustrate damage. A typical variety, “Dabaisha”, was considered in this study. were studied using test bench under different conditions. An orthogonal with three facto...

This paper presents a randomized manipulation planner for a multi-fingered hand by switching contact modes. Manipulation planning for such a system should consider changing kinematics and dynamics of the system according to the contact modes. We derive the conditions that would be satisfied in manipulation planning, based on the kinematical properties of a manipulation system. The conditions al...

Telomere shortening in primary human fibroblasts results in replicative senescence, which can be overcome by telomerase (hTERT) overexpression. However, because immortalization is one of the hallmarks of malignant transformation, careful analysis of hTERT-immortalized cells is of crucial importance for understanding both processes. To this end, we infected WI-38 fibroblasts with a retrovirus ca...

The key to the successful simulation of deformable objects is to model the realistic behavior of deformation when they are influenced by intricate contact conditions and geometric constraints. This paper describes constraint-based contact modeling between deformable objects using a nonlinear finite element method. In contrast to the penalty force based approaches, constraint-based enforcement o...
