DOI: 10.1088/1361-651x/ac5dcf
Abstract: A statistical analysis of internal stress fluctuations, defined as the difference between the local mean stress and stress on dislocations, is presented for deforming crystals with 3D discrete dislocation systems. Dislocation realizations are generated using… read more here.

DOI: 10.1088/1742-5468/aaf31c
Abstract: We provide a method for calculating time-averaged stress fluctuations on surfaces in a viscous incompressible fluid at equilibrium. We assume that (i) the time-averaged fluctuating stress is balanced in equilibrium at each position and that… read more here.
