Methods for Obtaining Forming Limit Diagrams of Material Defects

Abstract:

Forming limit is one of the important indexes to evaluate the formability of materials. In a variety of methods of evaluating the formability of materials, the forming limit diagram (FLD) is the most intuitive and effective, and the most widely used. There are many methods to obtain the forming limit diagram. This paper mainly introduces the methods for obtaining the forming limit diagram of the material defects, and material defects are classified into three categories: geometric defects, defects in organization structure and material constitutive defects, and the methods for obtaining forming limit diagram based on these three kinds of defects is analyzed and summarized.
