Question

Two previously undeformed cylindrical specimens of an alloy are to be strain hardened by reducing their cross-sectional areas (while maintaining their circular cross sections). For one specimen, the initial and deformed radii are 15 and 12 mm, respectively. The second specimen, with an initial radius of 11 mm, must have the same deformed hardness as the first specimen; compute the second specimen’s radius after deformation.

Answer 1

Answer:

Strain Hardening as name implies, physical straining of metal is induced to increase strength and thus load carrying capacity of the specimen under consideration. The level of straining is dependent on the increased strength required. Strains are classified into two as 'Lateral Strain' which is decrease of cross sections and 'Linear Strains' which is increase in physical extensions (usually 'length') of the specimen.
