Analisis de sensibilidad de formas en problemas estructurales con comportamiento no lineal del material

Abstract

This work describes the difficulties and considerations around sensitivity analysis when the material of the structure behaves non linearly. It is proposed a direct methodology to obtain such sensitivity in plasticity and damage structures. Moreover, a general solution to deal with the softening problem in structures is formulated obtaining values of sensitivity with physical sense. Several examples of applications explain the utility and benefits of the methods proposed.
