Strain-induced damage of metals under large plastic deformation: Theoretical framework and experiments

The interaction of dislocations and hydrogen-vacancy complexes and its importance for deformation-induced proto nano-voids formation in α-Fe

“…For example, several analytical models have been developed and extended to understand voids growth in alloys and steels (Benzerga et al, 2004;Fischer and Antretter, 2009;Khan and Liu, 2012;Lecarme et al, 2011;Li et al, 2011;Lou et al, 2014;Malcher et al, 2014;Tutyshkin et al, 2014). Besides experiments performed at microscopic level (Alinaghian et al, 2014;Tasan et al, 2014;Xu et al, 2015), some molecular dynamics simulations provided atomic view on growth of voids (Bringa et al, 2010;Traiviratana et al, 2008;Zhao et al, 2009).…”

Thin‐layer inertial effects in plasticity and dynamics in the Prandtl problem

“…For the normalized quantities, comma denotes a partial derivative in normalized coordinates, 1 , 2 , and . Also the normalized parameters, 1 ( ) and 2 ( ), which contribute to inertial terms, occur only in the equations of motion (16).…”

“…The works [14,15] are devoted to the viscoplastic analogue of the Prandtl problem and transition from a highly viscous fluid to a rigid solid. We also mention the similar generalizing investigations considering plastic flows with damage [16] and cyclic loading. [17] The formulae for stresses (9) and velocities (10) apply only if 1 > 0.…”

Effect of crystallographic orientation on stress evolution of the void in single crystal during uniaxial tensile creep

“…A unit cell containing a spherical isolated void with the radius of 0.1 mm at the center was employed. The side-length of the unit cell is five times of the radius of the void, and this geometrical size has been proved to be effective to reduce the boundary effect [8].…”

“…For ductile materials, the fracture process can be realized by the micro void coalescence in the front of crack tip. Various criteria and models have been proposed to capture this failure mechanism for various materials [5][6][7][8]. Besides, an extensive literature collection on void growth in isotropic materials exist beginning with slip line theory solutions [9][10][11].…”
