Towards high ductility in magnesium alloys - The role of intergranular deformation

, 2019
This paper investigates the intergranular deformation behavior and its effect on the overall ductility of a Mg-Gd-Y alloy, using in-situ tension in scanning electron microscopy (SEM) combined with electron backscattered diffraction (EBSD) and digital ...

Constant-ductility energy factors of SDOF systems subjected to mainshock–aftershock sequences

, 2020
This article focuses on the energy factor of single-degree-of-freedom (SDOF) systems subjected to mainshock–aftershock (MSAS) sequences, of which 163 and 143 are collected from crustal and subduction regions, respectively. The recorded MSAS sequences are

Factors affecting the shape of the ductile-to-brittle transition

International Journal of Pressure Vessels and Piping, 2002
Abstract This paper uses a statistical model of cleavage fracture to examine the effect of various material parameters on the mean toughnesses of ferritic steels in the transition region. Individually, changes in the flow properties, in the effective surface energy, and in the distribution of particles from which cleavage is initiated, all affect the

Ductility factors of symmetrical structures with restricted inelasticity

The Structural Design of Tall and Special Buildings, 2007
AbstractA simple elasto‐plastic analysis of symmetrical buildings composed of different types of bents is presented. Plasticity in bents is assumed to be restricted to the beams, where significant curvature ductility factors may be attained without loss of strength, and the behaviour of inelastic structures may be traced from elastic to ultimate ...

Factors governing strength and ductility of metallic composites

Proceedings of the Institution of Mechanical Engineers, Part L: Journal of Materials: Design and Applications, 2013
Two commercial Zn–Al alloys, constituting a natural composite consisting of ductile fibres of face-centred cubic aluminium in the less ductile close-packed hexagonal Zn-rich matrix, variously subjected to warm rolling and warm equal channel angular processing, were investigated to examine the factors governing strength and ductility.

Implications of microstructure, Taylor factor distribution and texture on tensile properties in a Ti-added Fe-Mn-Al-Si-C steel

Materials Science & Engineering: A, 2019
Structure-property relationship in a Ti-added medium Mn multicomponent steel has been studied and compared with a Ti-free variant of same composition. Both the steels with initial ferrite-austenite microstructure were subjected to cold rolling, followed ...

Effect of using CFRP wraps on the strength and ductility behaviors of exterior reinforced concrete joint

Composite structures, 2018
One considerable weakness in reinforced concrete (R.C) structures is the connection between beams and columns. Several researchers showed that R.C joints suffer brittle failure due to combined effect of loading on the joints.

Inelastic Displacement Amplification Factor for Ductile Structures with Constant Strength Reduction Factor

Advances in Structural Engineering, 2010
Based on elastic-plastic time-history earthquake analysis of the single degree of freedom (SDOF) system, the inelastic displacement amplification factor C d 2 of the elastic-perfectly plastic (EPP) model with the same yield strength reduction was investigated for different

Evaluation of behaviour factors on the basis of ductility and overstrength studies

Engineering Structures, 1999
The paper focuses on the evaluation of behaviour factors for seismic design of structures, with due consideration to both their ductility and overstrength. Firstly, inelastic strength spectra for typical target ductilities are presented for earthquake motions representative of those expected in Southern Europe, in particular Greece, the country with ...

Factors Affecting Ductile Fracture in Offshore Gas Pipelines

Offshore Technology Conference, 1982
Abstract This paper presents the results of experimental research conducted during the past three years with the objective of understanding ductile fracture propagation in the offshore environment. Experiments have been conducted to examine decompression phenomenon inside the carrier pipe when the exhausting gas is ...
