Constitutive models of steel under continuous casting conditions
(Elsevier Science Sa, 2003-12)
We review in this paper a series of constitutive equations that describe the behavior of steels at elevated temperatures, laying emphasis upon continuous casting processes. The different laws are situated in an appropriate ...
Modeling the mechanical response of a dual-phase steel based on individual-phase tensile properties
(2020)
In this work, the engineering stress-strain tensile curve and the force-deflection bending curve of two Dual-Phase (DP) steels are modeled, combining the mechanical data of fully ferritic and fully martensitic steels. The ...
Numerical modeling of steel fiber reinforced concrete with a discrete and explicit representation of steel fibers
(2019-03-01)
This work presents a novel numerical model based on the use of coupling finite elements to simulate the behavior of steel fiber reinforced concrete (SFRC) with a discrete and explicit representation of steel fibers. The ...
Objective Phenomenological Constitutive Law for Collapse Analyses in Distributed Plasticity Steel-Frame Models
(2021)
Nonlinear static and dynamic analyses are increasingly being used to evaluate the seismic performance of structures. The level of detail that mathematical models should include depends on the required analysis. In a collapse ...
Level of detail required to model special steel moment frames to evaluate floor accelerations in nonstructural components
(American Society of Civil Engineers, 2019)
The floor acceleration response of special steel moment frames (SMF) subjected to earthquakes has been evaluated by multiple investigations. It has been demonstrated that peak floor accelerations and floor spectra, which ...
The effect of the embrittlement on the fatigue limit and crack propagation in a duplex stainless steel during high cycle fatigue
(Elsevier, 2013-09)
In order to evaluate the effects that the “475° embrittlement” produces on the fatigue life during high-cycle fatigue, stress-controlled cyclic loading tests were conducted on a standard duplex stainless steel in two ...
Nitriding of AISI 4140 steel by a low energy broad ion source
(A V S Amer Inst PhysicsMelvilleEUA, 2006)
Multiscale modeling of steel fiber reinforced concrete based on the use of coupling finite elements and mesh fragmentation technique
(2018-01-01)
A multiscale model is proposed based on the use of coupling finite elements recently developed by the authors. This feature allows the use of the same strategy to deal with two problems of non-matching meshes addressed in ...
