[ 1 ] - بررسی توزیع انرژی ذخیره شده تغییر شکل در داخل پلی‌کریستال فلزی با استفاده از تئوری کریستال پلاستیسیته بر مبنای چگالی نابجایی

The stored deformation energy in the dislocation structures in a polycrystalline metal can provide a sufficient  driving force to move grain boundaries during annealing. In this paper, a thermodynamically-consistent three-dimensional, finite-strain and dislocation density-based crystal viscoplasticity constitutive theory has been developed to describe the distribution of stored energy and dislo...
