Photoelasticity was also used for visual examination of the plastic zone size.
Thus, movement of the plastic zone boundary is successfully simulated until elastic core completely disappears.
Even brittle adhesives must form a very small but finite plastic zone.
These plastic zone sizes are significantly smaller than the crack length, the uncracked ligament, and the specimen thickness.
The value (15) of the principal normal stresses are valid in plastic zone under the ideal conditions the plastic flow.
The TOM micrographs indicate no plastic zone for the neat resin, while a big plastic zone was observed for the blend containing CSR particles with 20 wt% MMA units in their copolymer shell.
It is known that the impression test is a localized test, which is associated with the evolution of the local plastic zone underneath the punch.
To go further, one can see that the mechanical behaviours resulting from the two types of treatments are radically different: the surface treatments tend to extend the elastic zone without increasing the plastic zone, whereas the main effect of coupling agents is to increase the plastic zone and slightly the elastic domain together with a weak decrease of the Young's modulus.
p] is the size of the plastic zone that can be estimated using the following equation:
