%X According to methodology of damage mechanics, the conservative integral, stress and strain concentration factors and closed form solution of fatigue crack initiation lives of notched plates are established. For aluminum alloy, the agreement between the results of theoretical predictions and those by experiments is satisfactorily good. This method is very time-saving and a lot of experimental work can be substituted.So this method is in engineering practice.
