2 aExprimental setup,bShear and compression specimens In order to determine the mechanical behavior of the Ti17 alloy under extreme conditions, both compression and shear tests have

The significant increase of the compressive stress and the changes in the mechanical properties hardness and elastic modulus observed at 50% nitrogen concentration in the plasma may be

Figure 12 shows the evolution of the residual stresses versus the depth be- low the machined and combined machined/treated surfaces obtained using the combined tool for a normalised

For all of these reasons, a Q4P1 shape function based on global DIC approach has been chosen for the present study, concerning the displacement field measurement during orthogonal

On the basis of these estimated models, three amplitude dependent damage indexes are built: one that monitors the shift of the resonance frequency of the structure, another the ratio of

3, a material model to predict theflow behaviour of the Inconel 718 should consider strain hardening up to a strain level of ~ 0.26 followed by a strain softening range where stress
