What is the material property that describes (a) in the graph above?

What is the material property that describes a material's tendency to contract laterally when stretched longitudinally? It is defined as the negative ratio of transverse (lateral) strain to axial (longitudinal) strain.

The following formula, , is utilized in designing materials in order to predict the fracture behavior when a crack is present, where K_IC is the plain strain fracture toughness, Y is a parameter accounting for the mode of fracture and geometries of specimen, s is the external stress and a is the crack size. Among the parameters in the formula, which is the one accounting for the manufacturing method applicable?
