Abstract
Plastic deformation of small-scale crystals proceeds through a sequence of intermittent plastic instabilities characteristic of strain bursts. In this work we construct the relation between second-order work and strain burst in single-crystalline micropillar plasticity. Based on energy conservation, theoretical analyses are performed on the relation between second-order work and strain burst. Furthermore, finite element analysis with the recently proposed intermittent plasticity model is employed to simulate the strain bursts and to compute their values of second-order work. Both the simulation results and the theoretical analysis show that the occurrence of strain burst corresponds to a vanishing of the second-order work. Finally, physical understanding of the relation between the second-order work and the strain burst is attempted.
