The effects of the degree of randomness of arrays of shearable particles on the critical resolved shear stress of particle strengthened materials Original Research Article

It has been investigated in computer simulations how the randomness (≙ irregularity) of the arrangement of particles in the glide plane affects the critical resolved shear stress (CRSS) of materials strengthened by shearable nano-scale particles. The result is that there is an overall increase of the CRSS with increasing degree of randomness, that is with decreasing regularity, but this increase is not monotonic.
