crack nucleation at the notches root and flat rupture when the clad is embrittled by hydrides at 25 °C, - inner surface cracks nucleation controlled by nearly pure shear at higher temperature. In both cases, the loading is not fully representative of the rupture conditions in RIA. The chara...
However, this kind of secondary surface marks have never been observed in tensile fracture tests, even for a crack velocity higher than 3000 m/s8. Hence, the SSM nucleation is likely related to the local crack velocity distribution under bending load. Front wave mechanism The local crack ...

In this case, there is a transition from notch-driven crack initiation to quasi-brittle crack nucleation in the material’s bulk. Fig. 2 Effect of increasing notch width on crack nucleation: Simulations of system size of Lx = 8 μm, Ly = 0.5 mm, and Lz = 1.0...

Condensation of the electron beam resulted in generation of local thermal stress on the composite film which ultimately results in crack formation and its propagation. The crack growth rate was controlled by controlling the electron beam flux. It was observed that nucleation of crack took place at ...
