Shell Mesh Based FE Analysis for Free Vibration Analysis of Radial Pneumatic Tire
The natural frequencies and mode shapes of pneumatic tires are predicted using a geometrically accurate, three-dimensional finite element modeling. Tire rubber materials and cord layers are represented independently using “shell element” available in COSMOS. The effects of some physical parameters such as the inflation pressure tread pattern, thickness of belts and ply angles to the natural ...

متن کاملAnisotropic Goal-Oriented Mesh Adaptation for Time Dependent Problems
We present a new algorithm for combining an anisotropic goal-oriented error estimate with the mesh adaptation fixed point method for unsteady problems. The minimization of the error on a functional provides both the density and the anisotropy (stretching) of the optimal mesh. They are expressed in terms of state and adjoint. This method is used for specifying the mesh for a time sub-interval. A...
متن کاملFully Anisotropic Goal-oriented Mesh Adaptation for Unsteady Flows
We present a new algorithm for combining a fully anisotropic goal-oriented mesh adaptation with the transient fixed point method for unsteady problems. The minimization of the error on a functional provides both the density and the anisotropy (stretching) of the optimal mesh. This method is used for specifying the mesh for a time subinterval from the state and the adjoint. The global transient ...
متن کاملFully Anisotropic Goal-oriented Mesh Adaptation for the Euler Equations
A main advantage of unstructured meshes, i.e., tetrahedral meshes, is their flexibility for generating elements with large shape and size variations everywhere in the domain. Moreover, an adequate adaptation of the mesh impacts favorably numerical schemes. Consequently, an automatic process to control the mesh generation is of main importance. This document describes a goal-oriented anisotropic...
