ABSTRACT:

Conventional constitutive equations defining the flow stress relationship with the allied parameters are independent of one or more parameters. So the combined effect of all the flow parameters on true stress cannot be imagined in the existing frame of reference. In addition the same set of arbitrary constants does not works for all true strain, strain and temperature values for such models and their equations, which further adds new drawbacks while working with these relations. The present article works to complete the relationship between such flow parameters and the equation has been validated to Al 2024 aluminum alloy.
