Effect of different tensile loading modes on deformation behavior of nanocrystalline copper: Atomistic simulations

Effect of void in deformation and damage mechanism of single crystal copper: a molecular dynamics study

“…Hence, the fluctuation in the stress-strain plots is noticed in figures 2(a) and (b). The observed finding of the serrated stress-strain curve is consistent with the deformation study of copper [39]. It is noted in figures 2(a) and (b) that the yielding in both the triaxial modes occurs at the axial strain (ε zz ) of 0.023 (at point P and R in the tensile and compressive stress-strain curves, respectively).…”

“…It has been evident that the deformation at a low strain rate allows the study of deformation mediated by the dislocations [11]. Most likely similar strain rate is used in many MD simulations [20,21,28,38,39]. The deformation process has been carried out at a constant temperature of 300 K using a canonical NVT ensemble.…”

“…Strain hardening reduces ductility, which increases the chances of brittle failure. Variation of fields of strains in the matrix generate dislocations and cross movement up to which the movement is restricted by grain boundaries, pinning obstacles and other dislocation networks and strain fields such as Cottrell atmospheres [12][13][14].…”
