External components of an automotive body are manufactured from a stamping of sheet metal plane resulting in a final product with variable thickness due to different levels of stretch and a heterogeneous distribution of residual plastic strain. Generally, these informations are not considered in numerical simulations of the product and may cause considerable errors in the analysis of stamped parts involving nonlinearities. This work aimed to simulate an event called palm-printing in an automobile fender, with and without the consideration of the final data of the numerical simulation of the stamping process (final thickness and residual plastic strain) and the results compared with those obtained experimentally. Results showed that the consideration of thickness and hardening from the stamping process can improve the correlation of final results in quasi-static nonlinear analysis. However, the results showed that the influence of the thickness reduction is so important as the hardening, especially in the correlation of the reaction force of the indenter, contrary to reports in the literature in cases of crash test simulation.

The search for alternative forms of energy that generate a lower emission of carbon dioxide and pollutants leads to an increase in biodiesel fuel production in Brazil. The corrosion of steel equipment is a major problem in biodiesel fuel plants. The methodology applied in the research includes a survey of operating conditions and failure history as well as collection and analysis of corrosion data obtained in installing AISI 316L electrical resistance probes at strategic points in the process. © 2016 Elsevier Inc.

Engineering Failure Analysis | Year: 2010

A comparison between laboratory test data on fatigue crack nucleation in a rear tow hook pin assembly of passenger vehicle and a computational methodology using commercial package software is presented. Fatigue damage is determined using local material response, measured during experimental tests. Experiments were performed simulating the actual conditions in the customer environment. Stress and strain were experimentally measured by using strain gages, bonded on the hook assembly. These experimental lives are compared with those obtained through numerical analysis using a commercial fatigue software. Fatigue analysis methods (S-N curves, rainflow counting and Miner rule) were used to determine the fatigue damage imposed on the component. Interpretation and evaluation of the measured strain and stresses, simulation tests and fatigue life assessments, on the basis of S-N curve, are described in this paper. © 2009 Elsevier Ltd.
