    • The area bounded by the stress-strain curve may be found by applying Green's theorem, viz. ∫C (fdx+gdy ) = ∫ ∫D ( x g- y f ) dxdy where the plane region D is bounded by the simple, closed curve C with f (x,y ), g (x,y ) defined on an open region containing D and having continuous partial derivatives there. For f=0, g=x, the theorem reduces to ∫C xdy = ∫ ∫D dxdy.
