The Zhurkov Method

Another variant of the activation energy approach (Eq. 11.40) is the Zhurkov method, sometimes referred to as the kinetic rate theory, which is based upon tests on more than 50 different materials including both metals and polymers (see Zhurkov, (1965)) and results in an equation for the time to creep to rupture given by. 

If the activation energy, E, is equal to the quantity, yo, the creep rupture time is independent of temperature and implies the existence of a common pole as shown in Eig. 11.20. That is. 

Various modifications of Zhurkov s equation have been suggested and a discussion of these can be found in Griffith, (1980). The Zurkov equation can be written in the form,
