Graphite stress strain curve

WebAug 10, 2024 · There are 4 major regions that a stress-strain curve can be divided into: Proportional limit; Yield limit; Strain hardening; Necking; Proportional Limit. In the proportional limit, the specimen material acts like a spring and any strain caused is completely reversible. On the stress-strain curve, this area is called the Hooke’s region.
