Data associated with the publication: Predicting Plastic Events and Quantifying the Local Yield Surface in 3D Model Glasses

Abstract

By applying the local yield stress (LYS) method to probe local regions of three-dimensional computational glass models, we confirm high correlations between the measured local yield stress and the plastic events when the parameterization of the method is properly optimized. Here we apply only the local probing that aligns perfectly with the loading on the boundary on each of the 10x10x10 testing sites throughout the 3 glass samples with variations in the probing region size as 2.5, 3.75, 5, 7.5 and 10 atomic distance. A thorough investigation is conducted on the anisotropy of the local yield surface at the location of the first plastic event in one glass with variations in the direction, triaxiality, rotation and orientation during probing. It indicates that the first triggered region does not align perfectly with the loading on the boundary, but is well-predicted by projecting the shear applied at the boundary onto the local yield surface.
