What is plane strain and where does it plot in the Flinn diagram?
What will be an ideal response?
Answer: Plane strain is where there is no shortening or extension
perpendicular to the plane containing the maximum
and minimum strain axes (X and Z), i.e. Y=1. Hence
(X/Y)/(Y/Z)=1 and X/Z=1 for constant volume plane
strain, which plots along the main diagonal in the Flinn
diagram. If volume change is involved plane strain
plots along an offset diagonal.
