Grain Size Regulation During LDH Test

Micro forming is a production technology of very small metal elements. This paper presents a concept of grain size regulation during LDH (Limit Dome Height) test. The proposed concept is based on an empirical formulation generated using the experimental results of SS304 and brass. An empirical model is helpful in predicting the load-stroke behavior of different metals. Particularly, results of iron, copper and nickel are demonstrated. Further the concept of control scheme is presented to predict the grain size of the material during micro forming.
