註釋

Experimental results are presented which shed light on the assumptions that have been made in several attempts to bridge the gap between the physical and mathematical theories of plasticity. The experimental results are compatible with, but do not neceassarily verify, the conception that plastic deformation in strain-hardening materials is primarily due to slip. Slip was observed to occur first in a few isolated grains as the stress level increased. The occurrence and spread of the slip lines suggested independent behavior of randomly oriented grains at low stress levels with interaction among grains increasing as the stress level increased.
