New design model of reinforced concrete beams in bending considering the ductility factor
(IBRACON - Instituto Brasileiro do Concreto, 2020-03-27)
Ductility is a recommended characteristic by different RC structures design codes around the world, such as ABNT NBR 6118 [2], ACI 318 [1] and EUROCODE 2 [4]. Despite the recommendation of ductility, the codes only define ...
Damage severity estimation of an elastoplastic single-degree-of-freedom oscillator from its ground and response acceleration
(Structural Control and Health Monitoring, 2014-01)
for the estimation of occurrence in time and severity of damage of a damped elastoplastic single-degree-of-freedom
oscillator from its absolute and ground accelerations, using ductility as the adopted damage index. This ...
Ductility analysis of RC beams considering the concrete confinement effect produced by the shear reinforcement: A numerical approach
(2017-01-01)
In this paper, a simplified numerical approach to study the influence of the confinement effect provided by transversal reinforcement on the ductility behavior of RC beams in bending is proposed. A unidimensional FEM ...
Experimental and numerical characterization of damage evolution in steels
(PERGAMON-ELSEVIER SCIENCE LTD, 2007)
This paper presents an experimental and numerical characterization of ductile damage evolution in steels subjected to large plastic deformations. To this end, a set of tensile tests combining load-unload tensile cycles is ...
A variational approach to the phase field modeling of brittle and ductile fracture
(2018)
The modeling of the post-critical behavior of materials is still a scientific challenge. This is especially true when dealing with materials that undergo complex behavior, in which several mechanisms are combined. This ...
Influence of Microshrinkage Cavities on the Plastic Deformation and Fracture Under Tensile Loading in Ferritic Ductile Iron
(American Foundry Society, 2021-07)
This work focuses on the study of the influence of microshrinkage cavities on the plastic deformation and fracture of ferritic ductile iron. Cast samples were especially developed to include dispersed microshrinkage. Tensile ...
Multi-scale analysis of the early damage mechanics of ferritized ductile iron
(Springer, 2017-03-18)
A multi-scale analysis of the linear elastic and the early damage stages of ferritic ductile iron is introduced in this work. The methodology combines numerical and experimental analyses in the macro and micro scales. ...
A ductile damage criterion at various stress triaxialities
(PERGAMON-ELSEVIER SCIENCE LTD, 2008)
The paper discusses the effect of stress triaxiality on the onset and evolution of damage in ductile metals. A series of tests including shear tests and experiments oil smooth and pre-notched tension specimens wits carried ...
