This paper deals with the level of detail that is necessary for representation of tread pattern in finite element tire models. Different methods for creation of tire tread mesh are systematized by two different criteria: the most common approaches and the finite element analysis type. Some of the representative approaches found in literature are given in more detail and their advantages and dis...

Abstract-An Eulerian finite element formulation is presented for problems of large elastic-plastic flow. The method is based on Hill’s variational principle for incremental deformations, and is ideally suited to isotropically hardening Prandtl-Reuss materials. Further, the formulation is given in a manner which allows any conventions finite element program, for “small strain” elastic-plastic an...

The aim of this contribution is to present numerical comparisons model-order reduction methods for geometrically nonlinear structures in the general framework finite element (FE) procedures. Three different are compared: implicit condensation and expansion (ICE), quadratic manifold computed from modal derivatives (MD), direct normal form (DNF) procedure, latter expressing reduced dynamics an in...

three dimensioned finite element analysis were conducted on concrete block paving. in order to verify the calculated results, an experimental case study was analyzed. good agreement was observed between the measured and the calculated results. based on the finite element analysis results and available failure models, comprehensive design charts were developed for port and industrial pavement wh...

In the present paper some implementation aspects of a parallel model for the solution of the large-scale systems deriving from non-conventional finite element formulations are presented. Results obtained when this implementation is used for conventional finite element formulation are also presented. A comparison is made between alternative variants of the Conjugate Gradient algorithm for the pa...

The convective hydrodynamic model of semiconductor devices is analyzed employing parallel and stabilized finite element methods. The stabilized finite element method for the two-carrier hydrodynamic equations and the parallel computational model are briefly described. Numerical results are shown for a bipolar transistor. A comparison of drift-diffusion, energy-transport and the hydrodynamic mod...

We got interested in the hypercircle method since it enables the derivation of reliable a posteriori error estimates without generic constants. It turned out, however, that it avoids also a loss of efficiency that we encounter when residual error estimators are used with the hp finite element method. Moreover, we obtain a priori error estimates for the comparison of different finite element fam...

The behavior a pneumatic tire is analyzed and simulated using a finite element model. We calculate the elastic deformations in the contact area of a pneumatic tire touching the street for different friction conditions between tire and street. The simulations are compared with the experimental results. The comparison demonstrates that the overall deformation as well as the frictional behavior in...

In this dissertation a moving mesh method finite element method is used to approximate moving boundary solutions to the shallow water equations. An Arbitrary Lagrangian Eulerian method is applied to an existing finite element scheme. Some exact solutions to the shallow water equations in a parabolic basin are shown for comparison. An investigation is conducted into the accuracy of the method. I...
