Identification for Technological Capabilities of Titanium and Aluminum Alloys in Deep Drawing Process

摘要

The paper describes a method which has been developed for obtaining the limiting drawing ratio of titanium and aluminum alloys, and determines the moment of failure of the work-piece. This method is based not only on the use of Forming Limit Diagram (FLD) in predicting the failure of the blank, but also the using method of variable parameters of elasticity in determining the stress-strain state in deep drawing process.
