TITLE
Review and Recent Developments in Physical Modeling of Metal Forming

ABSTRACT
In order to acquire a better understanding of metal forming processes, different analytical and experimental approaches have been developed. Analytical models such as mathematical models are cost effective, but there are difficulties encountered in arriving at an exact solution while analyzing complex metal forming processes, especially non-steady state processes. Experimental modeling techniques, thus, have been used for a very long time, and were continuously improved until today as a complementary tool. In fact the error of analytical models as e.g. finite element simulations with appropriate data is generally inferior to the inaccuracies that are introduced by using special simulation materials (wax, different metals, etc.) in experimental technique. In general, experimental techniques are complementary to analytical models. A development guide on physical modeling of metal forming could be of interest to researchers in the field. However, a comprehensive review could not be found on the subject. In this article the authors present an historical review of development of physical modeling techniques in metal forming, while recent developments in the field are of importance in the article.
