A ductile specimen that has an initial length of 10 cm is tested under uniaxial loading. If the test is under tension and the nominal strain is 21.9%, please calculate the true strain in %.
1.From the tensile stress-strain behavior for the brass specimen shown in below, determine the following: (a) The modulus of elasticity, (b) The yield strength at a strain offset of 0.002, (c) The maximum load that can be sustained by a cylinderical specimen having an original diameter of 12.8 mm, (d) The change in length of a specimen originally 250 mm long that is subjected to a tensile stress of 345 MPa.
"The maximum principal stress yield criterion is an appropriate choice for ductile materials but the maximum principal strain criterion is preferable". Is this true or false?
