Creep tests were performed on rat tail tendons at each of six temperatures: 25, 30, 35, 40, 45, and 50°C. It was found that the time interval from load application to rupture was related to the applied (specific) load and the temperature. Over the range 25° to 45°C this relation was found to be reasonably approximated by a Tobolsky-Eyring rate equation, if a squared term in specific load was added to the numerator of the exponent. Deviation of the 50°C data from this equation was hypothesized to be associated with incipient “melting”. The apparent activation energy for the failure process was sufficiently high to suggest that the creep failure of tendon involves the breaking of covalent bonds.
