Accelerated Degradation

  • J. W. McPherson


In Chap.  2 we learned that a stressed material was at a higher Gibbs Potential and therefore more unstable. The stressed material will spontaneously degrade, but at what rate? We might suspect, and rightfully so, that higher stress levels will make a material even more unstable and therefore accelerate the degradation rate; also, our intuition might suggest that the degradation rate for a material is temperature dependent. This chapter will develop the needed equations that show that this is indeed the case.
