This work is concerned with the modeling and numerical simulation of cyclic loadings in elastro-plastic structures. Na aditive decomposition of the continuum problem is used to develop stable and robust finite element techniques of solution:
-that consider a Constant stiffness matrix (exatly the same obtained in na equivalent elastic problem). This matrix is assembled and composed only once along the process of solution.
-in which the integration of the evolution Law is performed element-by-element.
The effectiveness and usefullness of the proposed numerical technique is verified by analysing the cyclic behaviour of AU4G aluminium alloy and 316 L stainless steel pressure vessels and trusses.
