Estimation of equivalent stresses and equivalents of the fatigue test programs of airframe composite elements by V. E. Strizhius

“…It is known that for metal components of aircraft structures, "equivalent stress" is one of the most important parameters used to assess the fatigue damage resistance of a structural element for a given program of its fatigue tests. The method and the procedure for estimating the values of this parameter for metal elements of aircraft structures are presented It is noted that for aircraft structural elements made of polymer composite materials, neither the concept of the "equivalent stress" parameter nor the methods for calculating estimates of the values of this parameter are currently defined in domestic and foreign studies of the fatigue strength of such elements. …”
