A realistic finite element model to RCF requires prior knowledge of cyclic response of material along with a reliable material model. As discussed earlier, during rolling contact fatigue, material undergoes cyclic plasticity which is accumulated at subsurface level over hundreds of million cycles along with the kinematic translation and radial
Oct 14, 2001 · Virtual reality based surgical simulators offer a very elegant approach to enhancing traditional training in endoscopic surgery. In this context a realistic soft tissue model is of central importance. The most accurate procedures for modeling elastic deformations of tissue use the Finite Element Method to solve the governing mechanical equations. A finite element method for crack growth without An improvement of a new technique for modelling cracks in the finite element framework is presented.

Recently, specimens geometry is usually designed by means of finite element analyses support [4-5]. Cyclic plasticity models available in commercial software are usually not enough A new approach to finite element modelling of flexible In both cases, an axisymmetric finite element modelling of the rotor is proposed which takes into account the 3dimensional nature of the system while keeping the number of degrees of freedom to a reasonable level. In order to perform the stability analysis, a preliminary reduction of the system is achieved using the component mode method.

In this paper, a new approach for modeling of three dimensional slope stability problems is presented. To this end, p-version of the finite element method together with large deformation hyperelastic-plastic formulation is utilized to model localized, continuous deformation that has been observed in failure mechanisms of slopes. Floor vibrations - SteelConstructionfoFinite element modelling is an approximation, in which a continuous structure is divided into a number of parts or elements. The accuracy of the solution is dependent on the number of elements into which the system is divided, but this has to be balanced against the longer computation time.
Mar 03, 2012 · To account for cyclic loading, a new approach called the stiffness degradation method is applied. The results of a parametric study show that the design criteria used can indeed ensure optimum pile performance under static and cyclic loads.
