( B ) A stress of 6.7 MPa is employed to one type of a polymer under constant strain . After 40 days at 20 ° C the stress is reduced to only 8.4 MPa . When the same polymer is heated to 40 ° C the relaxation time is 40 days . 1- Calculate the relaxation time constant for this material at 25 ° C ? 2- Estimate the stress after 50 days at 25 ° C ? 3- Estimate the stress relaxation activation energy for the same polymer .
For a given polymer, the activation energy for the stress relaxation was measured to be 59kj/mol. If the stress relaxation time for this polymer at 7 degree Celsius is 3150 seconds. What is the relaxation time at 110 degree Celsius
