Fatigue of metal structures has long been recognized as a random process, subject to significant uncertainties. To avoid excessive conservativeness, design and maintenance of such structures require explicit consideration of uncertainties in material

Analysis of RC structures subjected to seismic loads vary greatly around the world, from simplified static models to more advanced methods, which take account of real dynamic loads and the nonlinear response of structures. As a recent theory, lumped

It is assumed in this paper that energy dissipation is a two-phase phenomenon. During the pre-localization stage, dissipation is a continuous process. After localization, it is lumped in surfaces of zero volume. To describe this process, it is propos

This paper presents a finite element formulation for the analysis of softening in plane problems. The model is not based on the non-local or gradient-dependent approaches. It is an extension of lumped damage mechanics. Lumped damage mechanics, or LDM
