yep. Thets right. For obtaining fracture and breaking it's not enough to have only stress-strain curve. Type of data and options which you need to discover fracture depend on analisys type
@@FEAry_tales Thank you! Ss then if you have a general FEA with a nonlinear monotonic stress strain curve for standard steel (A36), at what percent of total or plastic strain would you say it has reached failure?
@@drury2d8 real curve depend from lot of nuances (even production types: plates, tubes...), heat treatment. Additionaly it depend from behavior (high speed impacts, fatigue, temperatures), so it is better to do real experiments to obtain curves for your conditions. But But in general, basic ASTM A36 as i can see from search will fail at ~25% of strain
Thank you for this video 👏
Glad it was helpful!
Plastic strain is 116% in 23:24? Is that because its a uniaxial monotonic stress strain curve that only predicts necking but not fracture?

I think, this video can be helpfull th-cam.com/users/shorts7au4mz6C6RQ
