True stress (σt) and true strain (εt) are used for accurate definition of plastic behaviour of ductile materials by considering the actual dimensions. |
The negative ratio of transverse strain (∆y/y0 or ∆z/z0) to axial strain (∆x/x0) is called Poisson's ratio . The symbol for Possion's ratio is ν (nu). ν = −, ∆y ... |
