Effect of compounding investigated theoretically by finite element modeling. The variables are interference radius & shrinkage tolerance. Equivalent von Mises stress is used as yield criterion to evaluate the optimum interference radius. For two different working pressure the effect of the ratio of outer & inner radius (b/a=k) value on the optimum interference radius is also noticed. The optimum interference radius solely depends on shrinkage tolerance. Furthermore, percentage reduction of von Mises tolerance is compared for different working pressures & different k values as well as for different materials.
