,Prediction of Optimal Lifetime of the Tool’s Wear in Turning Operation of AISI D3 Steel Based on ththe spectral center of gravity. The SCG spectral indicator has shown its power of predicting the transition from the phase of normal wear to that corresponding to the catastrophic wear of the cutting tool. The results obtained allowed to study the phenomena of vibration and then to predict their opt

The Evaluation of the Dynamic Response of the Moving Exciter Due to the Irregularities of the Slab,differential equations of the free motion of the path surface to be solved and enables it to be incorporated into structural analysis software, as there is no required integration. This is a major advantage over approaches that rely upon a Rayleigh-Ritz method and is demonstrated an interactive soft

Industrial Reproduction of Objects with Freeform Surfaces Using Reverse Engineering Process,nd particularly in zones of high curvature variations. Consequently, the analysis of object surfaces to duplicate is a critical operation before scanning. In the same time, clouds of points must have optimal densities to facilitate their treatment and to minimize processing times. To validate the ge

Effect of Boundary Conditions and Damping on Critical Speeds of a Flexible Mono Rotor,tions. For this, we have taken the cases where the rotor is simply-simply supported, free-simply supported and free-free and we wanted to see their effect on the vibratory behavior by determining critical speeds and responses to synchronous and asynchronous forces. It was found that the damping affe

Remaining Life Estimation of the High Strength Low Alloy Steel Pipelines by Using Response Surface the uncertainties of the engineering model parameters through their probabilistic densities. The assessment of the stress intensity factor is conducted by using the finite element methods. The estimation of the reliability index and the probability of failure are carried out by coupling the mechani

Periodic Inspection Policy for a System with Two Levels of Degradation, level is the criti-cal degradation, threshold that causes system failure. Secondly, the economic model of the inspection/replacement policy, in the sense of minimizing the total cost of maintaining the system in a replacement cycle, was developed. Finally, a numerical and graphical analysis of the
