IPL-Exponential


The IPL-exponential model can be derived by setting [math]\displaystyle{ m=L(V) }[/math] in Eqn. (inverse), yielding the following IPL-exponential [math]\displaystyle{ pdf }[/math] :


[math]\displaystyle{ f(t,V)=K{{V}^{n}}{{e}^{-K{{V}^{n}}t}} }[/math]


Note that this is a 2-parameter model. The failure rate (the parameter of the exponential distribution) of the model is simply [math]\displaystyle{ \lambda =K{{V}^{n}}, }[/math] and is only a function of stress.

IPL-exponential failure rate function at different stress levels.
