A cylindrical specimen of brass that has a diameter of 20 mm, a tensile modulus of 110 GPa, and a Poisson's ratio of 0.35 is pulled in tension with a force of 40, 000 N. If the deformation is totally elastic, what is the strain experienced by the specimen along the lateral direction?
For some metal alloy, a true stress 345 MPa (50040 psi) produces a plastic true strain of 0.02. How much will a specimen of this material elongate when a true stress of 418 MPa (60630 psi) is applied if the original length is 500 mm (19.69in) ? Assume a value of 0.22 for the strain- hardening exponent, n
A strip of metal is originally 5 m long. It is stretched in 3 steps: first to a length of 6
m, then to 7 m and finally to 8 m. The original cross section area of the metal strip is
40 mm?. Compute the final cross section and find the percentage reduction in area
due to the above stretching process. Also calculate the force required for the final
stage of stretching, assuming that the true stress true strain relation for the
material is given as o = 700 0.48 MPa.
