Is there a way to use a custom crack growth equation (Walker, Forman, NASGRO, etc)? The reason is that I already have those material constants.

  Since Release 2020R2, you can also use the Walker equation and also Forman equation instead of just Paris’ law as a crack growth law. And you can define the crack growth law material parameters as temperature dependent values. It is currently not possible to define your own custom crack equation in equation form. BUT, also since 2020R2, you can define the crack growth law in TABULAR FORM (with linear interpolation between the data points in the log-log space). Further details you will find in the ANSYS Help at https://ansyshelp.ansys.com/account/secured?returnurl=/Views/Secured/corp/v202/en/ans_frac/franundcgrowmech.html and https://ansyshelp.ansys.com/account/secured?returnurl=/Views/Secured/corp/v202/en/ans_frac/fracSMART.html .
