The stress - strain behaviour of copper over a large strain range

WebThe Young’s modulus ( E) is a property of the material that tells us how easily it can stretch and deform and is defined as the ratio of tensile stress ( σ) to tensile strain ( ε ). Where stress is the amount of force applied per unit area ( σ = F/A) and strain is extension per unit length ( ε = dl/l ). Since the force F = mg, we can ... http://skb.se/upload/publications/pdf/R-09-14.pdf Webpercent ( ε = 0.001) or 0.2 percent ( ε = 0. 002) and the stress-strain curve itself. The total strain at any point along the curve in Fig. 5.3 is partly plastic after yielding begins. The amount of elastic strain can be determined by unloading the specimen at some deformation, as at point A. When the load is removed, the specimen shortens by an teamworld binghamton ny
