A comparative study on finite elements for capturing strong discontinuities: E-FEM vs X-FEM

On the basis of a comparative study, this paper aims to determine the maximum loads that can occur in operating conditions on the cardanic transmission assembly of motor vehicles in the open or closed loop configurations. The research is conducted under static conditions using finite elements and shows the components with their maximum values obtained in normal operating conditions.

Pavement Damage

The present work grants a study of technical development under a differentiated aspect where an extra tire was added to the standard double axle recommended by the Brazilian traffic calculation norms. The number N generated a triple axle, and a comparative study was made relating the balance load standardized in Brazilian balance laws for each type of axis and the damage generated on the pavement, measuring the results on a pavement chosen as a model, usually used on Brazilian highways. We verified through computer software, which uses the methodology of the theory of finite elements, supervised by the inspection bodies of the National Department of Transport infrastructure, proving if a larger amount of cargo generates the same damage to the pavement without jeopardizing its useful life, which was initially designed to last ten years.

Standard Calculation

The purpose of this paper is to validate the accelerated testing methodology of a component from the field of aviation (supple platinum) using the standard calculation method and the analysis with finite elements. The specimens made out of supple platinum from the helicopter’s structure have been put through to accelerated experiments. Using the data resulted from the analysis with finite elements, the data resulted from resistance calculations and the experimental data obtained from the testing of specimens, a comparative study was realized between the specific strain and the normal stress that were obtained. From the results of this comparative study, it is obvious the fact that the method of analysis with finite elements is an efficient instrument to validate the experiments.
