A copper rod with a diameter of 24 mm is subjected to tension within the elastic region. If themodulus of elasticity is 115 GPa and a Poisson’s ratio of 0.34. Determine the force that willproduce a reduction of 0.003 mm in the diameter.
A copper rod is deformed using a uniaxial tensile force of 16000 N. Deformation continues until sufficient strain hardening has occurred such that the applied force is too small to allow further deformation. After deformation, the rod has a diameter of 0.01 m and a length of 1.5 m. Assume that copper follows the strain hardening lawwith K of 310 MPa and n=0.54
Please calculate the true strain after the deformation ?
