Question:
The following data were obtained from a creep test for a specimen having a gage length of 2.0 in. and an initial diameter of 0.6 in. The initial stress applied to the material is 10,000 psi. The diameter of the specimen at fracture is 0.52 in.
Determine
(a) The load applied to the specimen during the test;
(b) The approximate length of time during which linear creep occurs;
(c) The creep rate in in./in. / h and in %/h; and
(d) The true stress acting on the specimen at the time of rupture.
