Unformatted text preview: curve at approximately 150 MPa (21,750 psi). (d) The tensile strength is approximately 240 MPa (34,800 psi), corresponding to the maximum stre-ss on the complete stressstrain plot. (f) The ductility, in percent elongation, is just the plastic strain at fracture, multiplied by 100. The to-tal fracture strain at fracture is 0.110; subtracting out the elastic strain (which is about 0.03) leaves a plastic strain of 0.107. Thus, the ductility is about 10.7%EL....
