Abstract
Most fabricated metal shapes in several products and components used in industry have anisotropic properties. This study deal with the triaxiality based mathematical models developed for Mode I fracture using Hill’s von Mises' yield criterion, for an anisotropic material having orthotropic symmetry. R (ratio of width strain to thickness strain) in case of anisotropy is the utility factor therefore on the basis of Rvalue the model for stress triaxiality is formulated and then compared to isotropic model in plane stress and plain strain condition. Criticality of M (stress triaxiality) is validated to plastic zones at each step. Keywords- R (strain ratio), Triaxiality, von Mises Yield criterion, Hill-von Mises yield criteria, Mode-I fracture
