Good day everyone! i have a problem dealing with the fracture analysis. We all know that the work done per unit volume is equal to the area under the curve of stress-strain curve or we can express it in terms of integral form, and if we're looking at necking point stress can be express in this terms of stress = constant*(strain)^n
where n is the work-hardening, but if we extend it up to fracture i don't know the expression for the stress and strain. So guys please help me figure out the work done up to fracture. Thank you!
