The lower bound of the endurance limit, defined as the maximal Hertzian pressure that does not induce any micro-plastic strain around inclusions, is computed for groups of inclusions in a bearing steel subjected to contact stresses. An extension of t

A new method has recently been developed for obtaining the local micro-plasticity properties of materials from nano-indentation measurements. This method is based upon the measurement and analysis of remanent displacement e r versus the maximum load

The cyclic mechanical behaviour of a high strength sintered steel was investigated. During the fatigue tests on notched specimens, the details of the crack propagation were surveyed by light or scanning electron microscopy. Those observations and the

The initiation and development of damage inside a 6061 Al alloy reinforced with SiC particles has been studied during in situ mechanical tests using high resolution synchrotron X-ray tomography. The high coherence of the X-ray beam used improves the

The plastic flow process around a spherical dilatated inclusion has been previously sketched as a “dislocation shell” emission idealizing patterns of collectively moving prismatic circular loops. This elastic description of relaxation is here rei

Microscopic mechanisms controlling the fatigue damage in 7010 aluminum alloy are analysed. Cracks are initiated by the fracture of second-phase particles. Particles located in grains with a twisted cubic texture have been observed as preferential dam

Pulsed DC electromigration (EM) tests up to 1 MHz have been performed on single level Al-0.5%Cu metallization. The results are in good agreement with an average current model when the Joule heating has been taken into account with an original thermal
