Tensile toughness (or, deformation energy, UT) is measured in units of joule per cubic metre (J·m ) in the SI system and inch-pound-force per cubic inch (in·lbf·in ) in US customary units. 1.00 N·m.m ≃ 0.000145 in·lbf·in and 1.00 in·lbf·in ≃ 6.89 kN·m.m . In the SI system, the unit of tensile toughness can be easily calculated by using area underneath the stress–strain (σ–ε) curve, which gives tensile toughness value, as given below: WebA rod is 2 m long at a temperature of 10 C. Find the expansion of the rod when the temperature is raised to 80 C. If this expansion is prevented, find the stress induced in the material of the rod. Take E = 1.0 x 105 MPa and alpha = 0.000012 per degree ce. A spring has a spring constant of 10 N/m. WebFracture strength is the value corresponding to the stress at which total failure occurs.
