A steel specimen is tested in tension. The specimen
is 2 in. wide by 2.3 in. thick in the test region. By
monitoring the load dial of the testing machine, it was
found that the specimen yielded at a load of 30 kips
and fractured at 40 kips.
a) Determine the tensile stress at yield and fracture;
b) If the original gauge length was 4 in., estimate
the gauge length when the specimen is stressed
to 2 the yield stress.
A mild steel specimen originally 300 mm long is pulled in tension with a stress of 500 MPa. If the deformation is entirely elastic, calculate the resultant elongation? The modulus of elasticity of steel is 200 GPa.
A steel specimen is tested in tension. The specimen is 25 mm wide by 12.5 mm thick in the test region.
