CONSIDERAZIONI TEORICHE E PRATICHE SUL METODO DEL MASSIMO RETTANGOLO CIRCOSCRITTO PER LA VALUTAZIONE DELL’AMPIEZZA DELLA TENSIONE TANGENZIALE NEI CRITERI DI FATICA MULTIASSIALE BASATI SULL'APPROCCIO DI PIANO CRITICO

[automatically translated] The multiaxial fatigue based on the approach of critical plane criteria require the determination of the amplitude voltage alternating tangential a agent on different planes through the point of the material analyzed. In the case of non-proportional type stresses the vector of the tangential voltage varies both in magnitude and in direction and its tip describes a defined load path curve. In these cases a is evaluated by means of special procedures of which the most recent and seemingly more effective is that of Massimo Circumscribed Rectangle (MRC) to load the same path. In this work a comparison is made between the MRC and the main method other methods in terms of results and computational burden,
