Hello every body
I am working on the simulation of micromachining of โglassโ in abaqus.
Although the glass is brittle, it shows some plasticity in micromachining
because of the high hydrostatic pressure field present in the machining region.
Now I am looking for an appropriate material model for glass with
elasto-plastic behavior which allows element deletion. I am not sure if "johnson-Holmquist damage model" is suitable for machining simualtion or not? I would be very thankful
if anyone would please help me.
With best regards
Farzad
