Finite Element Analysis of Safety Mechanism in a Mechanical Controller

In this study, dynamic behavior of safety mechanism of a mechanical controller is investigated using 3D-FE simulation. This paper is concentrated on controller of a high acceleration projectile. The controller is located in the top of the projectile. Safety mechanism is divided to deformable and rigid parts. Deformable and rigid parts are simulated in Abaqus and Adams commercial soft wares; res...

Analysis of Roll Wear in Reshaping Using Finite Element Simulation

Reshaping process is a widely used method for producing tubes with non-circular cross sections. Owing to the friction between pipe and rolls, initial round pipe moves forward and consequently, it gradually formed into square or rectangular one. In practice, geometric profile of the rolls will be changed after a while. These changes would be detrimental the production of faultless products. Ther...

Finite Element Models for Mechanical Simulation of Coronary Arteries

The constitutive model considered is anisotropic with the parameters proposed by [6], as follows, where subindex (•) M is used for the media and (•) A for the adventitia: c M = 27.0 kPa, k 1M = 0.64 kPa, k 2M = 3.54, K M = 10 4 kPa, φ M = 80 o , c A = 2.7 kPa, k 1A = 5.1 kPa, k 2A = 15.4, K A = 10 4 kPa and φ A = 50 o. The mesh comprises 5184 hexahedral elements with 7040 nodes and 20352 degree...

3D Finite Element Simulation of Graphene Nano-Electro-Mechanical Switches

In this paper, we report the finite element method (FEM) simulation of double-clamped graphene nanoelectromechanical (NEM) switches. Pull-in and pull-out characteristics are analyzed for graphene NEM switches with different dimensions and these are consistent with the experimental results. This numerical model is used to study the scaling nature of the graphene NEM switches. We show the possibi...
