Ductility and shear demands in reinforced concrete buildings with asymmetric walls
(2017)
This research aims to obtain envelopes of the ductility and shear demands in reinforced concrete (RC) wall buildings subjected to ground motions. These envelopes could be used in the future to provide design recommendations ...
Mechanical characterization of dual phase austempered ductile iron
(Iron Steel Inst Japan Keidanren Kaikan, 2010-02-20)
The fatigue behavior and mechanical properties of Dual Phase Austempered Ductile Iron (Dual Phase ADI) containing 20, 50, and 70% ausferrite were studied and compared to ductile irons with fully ferritic and ADI matrices. ...
High silicon ductile iron: possible uses in the production of parts with ?dual phase ADI? microstructure
(Iron Steel Inst Japan Keidanren Kaikan, 2012-02)
The aim of this paper is to study the advantages and disadvantages of using high silicon ductile iron to produce cast parts with "Dual Phase ADI" microstructure. In this study, four ductile irons with different percentages ...
Analysis of mechanical properties and its associated fracture surfaces in dual-phase austempered ductile iron
(Wiley Blackwell Publishing, Inc, 2013-04-11)
This work aims at evaluating the fracture surfaces of tensile samples taken from a new kind of ductile iron referred to as ‘dual-phase Austempered Ductile Iron (ADI)’, a material composed of ausferrite (regular ADI ...
A Microscale Model for Ausferritic Transformation of Austempered Ductile Irons
(Springer, 2016-10)
This paper presents a new metallurgical model for the ausferritic transformation of ductile cast iron. The model allows predicting the evolution of phases in terms of the chemical composition, austenitization and austempering ...
Boundary element analysis of fatigue crack propagation micromechanisms in austempered ductile iron
(Elsevier, 2001-07-01)
The Dual Boundary Element Method (DBEM) is used in this work to model the micro mechanics of fatigue crack propagation in austempered ductile iron (ADI). Emphasis is put in devising accurate procedures for the evaluation ...
Determination of effective elastic properties of ferritic ductile cast iron by computational homogenization, micrographs and microindentation tests
(Elsevier, 2015-01-12)
A comprehensive procedure for the prediction of the elastic behavior of ferritic ductile iron by means of multiscale analysis is introduced in this work. The procedure combines computational procedures for the homogenization ...
Ductile tensile failure in metals through initiation and growth of nanosized voids
(Elsevier, 2012-06)
We here reveal the initiation of ductile failure in metals at the nanometer scale by molecular dynamics simulations coupled with a novel analytical model. This proceeds by the emission of a special type of dislocation shear ...
Influence of alloy element distributions on austempered ductile irons
(Maney Publishing, 2018-11)
The influence of alloy element distributions on austempered ductile iron microstructure and austempering treatment was analysed by a cellular automaton model that considers the ausferritic and martensitic transformations. ...
