Abstract

A method of computing dynamic load factor under harmonic load is suggested. The method is based on the representation of the dynamic stress intensity factors in form corresponding to normalized free vibration modes with some weight coefficients and then determine dynamic load factor of 2024-T3 alloy. The motion equation is solved by ANSYS program to determine the effect of harmonic loading on dynamic load factor and fracture toughness from another side.
