The present invention relates to a method of simulating the performance of nuclear fuel, comprising a first step of inputting an initial value of a nuclear fuel stress strain ratio; a second step of calculating an effective stress by applying an effective-stress-function (ESF) algorithm to the initial value; and a third step of repeating the second step by using the effective stress as a new initial value if the calculated effective stress is not in a balanced state.
