文摘

Modified strain energy density exhaustion is considered in the present model. The present model is more accurate by using the cycle-by-cycle concept. Nickel-based GH4169 superalloy at 650 °C is employed to verify the proposed model. The history-dependent accumulated damage is monitored in the interaction diagram.
