Abstract
Official abstract text for this publication.
According to exemplary embodiments of the present invention, using a fracture limit stress line obtained by converting a hole expansion ratio into a stress as a criterion for a fracture, the risk of fracture in a material can be evaluated quantitatively by comparing the relationship between data obtained from a numerical analysis using a finite element method and the fracture limit stress line. Thus, when determining a fracture limit in a stretch flange portion in a thin plate in a process including one or more deformation path variations, it is possible to obtain the fracture limit curve easily and efficiently and predict the fracture with high accuracy, and the risk of fracture upon press forming or crash can be evaluated.
First claim
Opening claim text (preview).
What is claimed is: 1. A non-transitory computer-accessible medium having instructions thereon for evaluating a particular fracture limit and a fracture likelihood of a thin plate which is a solid thin plate that includes a metal material, wherein when a hardware processing arrangement executes the instructions, the hardware processing arrangement is configured to perform procedures comprising: convert a first fracture limit curve which changes depending on a deformation path in a…
