Refined Vehicle-Bridge Interaction Analysis Using Incompatible Solid Finite Element for Evaluating Stresses and Impact Factors

Impact Stresses in Flapper Valves - A Finite Element Analysis

Impact stresses in flapper valves have been calculated on the basis of a finite element analysis. The impact velocity at initial contact used in the present calculations, 8 m/s, has been taken £rom previous high speed photographic measurements. Our calculations indicate that the final impact velocity at oblique impact exceeds 8 m/s significantly. This "whip-lash effect" gives rise to higher imp...

Development of an efficient finite element model for the dynamic analysis of the train-bridge interaction

The design of high-speed railway bridges comprises a set of demands, from safety and serviceability aspects, to new types of equipment and construction solutions. In order to perform an accurate and realistic evaluation of the corresponding dynamic behavior, adequate analysis tools that take into account the complexity of the train-bridge system are required. These computational tools must be b...

Free and forced vibration analysis on finite element model of an off-road vehicle

In the present paper, the modal analysis on a full finite element model of an off-road vehicle. This vehicle was modeled in the CATIA software and then meshed in the HYPERMESH software. The free vibration analysis was conducted by the ABAQUS software. By applying an external displacement, the forced vibration analysis was also performed. As a result, natural frequencies and shape modes were ext...

Analysis of Finite Element Methods and Domain Decomposition Algorithms for a Fluid-Solid Interaction Problem

This paper concerns with the nite element Galerkin approximations for a uid{ solid interaction model proposed in [10]. Both Continuous{time and discrete{time approximations are formulated and analyzed. Optimal order a priori estimates for the errors in L (H) and L(L) are derived. The main di culty for the optimal order error estimates is caused by the interface conditions which describe the int...
