689: 22: 269:-value between 0.10 and 0.50. In one study, strain hardening exponent values extracted from tensile data from 58 steel pipes from natural gas pipelines were found to range from 0.08 to 0.25, with the lower end of the range dominated by 111:. This characteristic is what sets ductile materials apart from brittle materials. The uniaxial tension test is the primary experimental method used to directly measure a material's 166: 212: 188: 324: 304: 267: 236: 97: 726: 540:"Automated Calculation of Strain Hardening Parameters from Tensile Stress vs. Strain Data for Low Carbon Steel Exhibiting Yield Point Elongation" 644: 599: 40: 58: 745: 719: 671: 270: 619: 755: 215: 712: 127: 108: 103:(work hardening) is the process by which a material's load-bearing capacity increases during plastic (permanent) 99:, is a measured parameter that quantifies the ability of a material to become stronger due to strain hardening. 750: 112: 591: 135: 274: 123: 241:
