Narayanasamy, M. Ravi chandran, C. Sathiya Narayanan, N. Parthasarathi, R. Ravindran] In this paper, the influence of annealing temperature on formability, fracture behavior, void nucleation, its growth, and coalescence are studied. The voids and fracture behavior are studied as a function of various void parameters, namely δd-factor (ligament thickness between consecutive voids), d factor (ratio of δd and radius of the void), void area fraction (Va) and L/W ratio (ratio of length to width of the void). The L/W ratio of the oblate or prolate voids at fracture is correlated with the mechanical properties, microstructure, minor strain at fracture (ε2), Mohr's circle shear strains, stress, and strain triaxiality factors. The Lode factor (θ) is determined and correlated with the Stress triaxiality factor (T), which is the ratio of mean stress (σm) to effective stress (σe). In addition, the Void area fraction (Va), which is the ratio of void area to the representative sample area, is determined correlated with the Strain triaxiality factor (To). It is found that the sheets annealed at 300°C, possesses better formability due to lower d-factor, higher $$ \overline n $$ and $$ \overline r $$ -values, greater void area fraction and lower L/W ratio of void accommodating more plastic deformation.
