A characterization and critical discussion of models and their use in environmental policy
Formal models, most of them implemented with computers, play a critically important role in the development, implementation and enforcement of environmental regulatory policy. As in the social sciences, some of these models serve as research tools which are useful in developing and testing theoretical insight. But a large set of models are used directly in the day-to-day processes of impact assessment, policy-formulation, and most importantly, regulatory enforcement.
In the present work, Von Mises criterion and its distortional energy density interpretation proposed for plastic mechanics is employed to study the effect of temperature on plastic yielding behavior of metal
