متن کاملThe nonlinear mechanics of slender structures undergoing large deformations
The deformation of slender structures (i.e., structures that are much longer in one direction than in the other two directions) may be described by elastic rod theory if one is interested in phenomena on length scales much larger than the lateral dimensions of the structure. A simplified version of this theory, beam theory, suffices if only small deformations need to be considered. Many traditi...
متن کاملNonlinear Dynamics of an Electrically Driven Impact Microactuator
We study the dynamics of an electrostatically driven impact microactuator. Impact between moving elements of the microactuator is modeled using the coefficient of restitution. Friction between the microactuator and its supporting substrate is modeled using the Amonton-Coulomb law. We consider the bifurcations under changes in the driving voltage and frequency. Grazing bifurcations introduce dis...
متن کاملLarge bending deformations of pressurized curved tubes
In this paper, the problem of large pure bending deformations of membrane is considered. The membrane is a sector of torus with a closed cross-section. This membrane is called a curved tube for short. We consider the homogenous, incompressible, isotropic and hyperelastic material. The external load is a constant pressure and bending couples acting at the edges. The equilibrium equations reduce ...
