moulding tool die life calculation

If the life that you are referring to involves abrasive wear, itmay be difficult obtaining a very predictive model; however, youcan definitely use the tool to estimate fatigue life for structuralcomponents of your die set under fatigue loading.
For wear related studies, you can play with setting up contactswith friction coefficients and make some assessment of thestate of stress at the surface.  If you can provide some moredetails on the type of assessment you are trying to make, we canprovide better details on the possibilities.
