The Finite Element Model

When creating porous materials, one of the tasks is to increase the insulating properties of products made from such materials. The properties of the porous material depends on the geometry of the pores and their relative position. Another area of use of porous materials is associated with their use for filtration. Thus, it is necessary to be able to obtain the results of virtual tests of the porous structure for the study of fluid flow in this structure or patterns of the distribution of temperature fields in the material.In both cases, to perform the simulation, you must first create the geometric part of the finite element model. Note that in the first problem, the geometric region is the material of the pores, and in the second case, the liquid contained in the pores.

Abstract A finite element model was developed to simulate the tire-rim interface. Elastomers were modeled by nonlinear incompressible elements, whereas plies were simulated by cord-rubber composite elements. Gap elements were used to simulate the opening between tire and rim at zero inflation pressure. This opening closed when the inflation pressure was increased gradually. The predicted distribution of contact pressure at the tire-rim interface agreed very well with the available experimental measurements. Several variations of the tire-rim interference fit were analyzed.

Torsional Analysis

Abstract A three-dimensional (3D) beam finite element model was developed to investigate the torsional stiffness of a twisted steel-reinforced cord-rubber belt structure. The present 3D beam element takes into account the coupled extension, bending, and twisting deformations characteristic of the complex behavior of cord-rubber composite structures. The extension-twisting coupling due to the twisted nature of the cords was also considered in the finite element model. The results of torsional stiffness obtained from the finite element analysis for twisted cords and the two-ply steel cord-rubber belt structure are compared to the experimental data and other alternate solutions available in the literature. The effects of cord orientation, anisotropy, and rubber core surrounding the twisted cords on the torsional stiffness properties are presented and discussed.
