An algorithmic approach for peak load evaluation of structural elements obeying a Menetrey-Willam type yield criterion

Aurora Angela Pisano

Abstract:
A numerical procedure for the evaluation of the peak load of a general class of structures is presented. Namely the addressed structures obey to a three stress invariants constitutive criterion of Menetrey-Willam-type endowed with cap in compression. The formulation, developed in the Haigh-Westergaard coordinates, allows an easy treatment of the mechanical problem in a 3D context as well as an interesting geometrical interpretation in the principal stress space.
