Methods of analysis of a reinforced concrete section under bending with axial force in the post-yield range

open access: yesBudownictwo i Architektura, 2014
Predicting the behaviour of plastic hinges subjected to large inelastic deformations caused by extreme loads such as earthquakes plays an important role in assessing maximum stable deformation capacities of framed concrete structures. This paper presents

Brittle‐ductile coupling: Role of ductile viscosity on brittle fracturing [PDF]

open access: yesGeophysical Research Letters, 2005
Localized or distributed deformations in continental lithosphere are supposed to be triggered by rheological contrasts, and particularly by brittle‐ductile coupling. A plane‐strain 2D finite‐element model is used to investigate the mechanical role of a ductile layer in defining the transition from localized to distributed fracturing in a brittle layer.

Parametric Investigation of Cyclic Behavior of Bolted End plate Connections [PDF]

open access: yesJournal of Structural and Construction Engineering, 2020
بررسی دقیق عملکرد اتصالات در یک سازه فولادی از اهمیت ویژ‌ه‌ای برخوردار است و عدم دقت در طراحی و اجرای اتصالات، نه تنها موجب خرابی خود اتصال می‌شود بلکه اثرات ویران‌کنندهای نیز بر سایر اعضای سازه خواهد داشت.

Ductile steel fibre composites with brittle and ductile matrices [PDF]

open access: yesComposites Part A: Applied Science and Manufacturing, 2014
Abstract Due to the intrinsic brittleness of high performance fibres, traditional structural fibre-reinforced composites have limited ductility and toughness. In the present work a new class of fibres is explored for the reinforcement of polymers: continuous stainless steel fibres that simultaneously possess a high stiffness and a high strain-to ...

Ductility enhancement of geopolymer concrete columns using FRP confinement [PDF]

open access: yes, 2016
Geopolymer concrete is an environmentally friendly, green construction material. However its use is constrained by its increased brittleness and lack of understanding of its behaviour under multi-axial loadings.

Ductility enhancement of layered stainless steel with nanograined interface layers [PDF]

open access: yes, 2012
Combination of surface mechanical attrition treatment (SMAT) and co-rolling is a promising experimental methodology to design metals with high strength and high ductility.

Superior strength-ductility synergy by hetero-structuring high manganese steel

open access: yesMaterials Research Letters, 2020
Lacking of forest hardening makes low ductility in steels long challenge particularly at high yield strength. Here, we report to make good use of hetero-structuring for superior strength-ductility synergy in high manganese steel.

Flexural Behavior of Post-Tensioned Concrete Beams with Multiple Internal Corroded Strands

open access: yesApplied Sciences, 2020
The corrosion of prestressing steel in prestressed concrete bridges is a critical safety issue. To evaluate the strength of a prestressed concrete beam with corroded strands, it is necessary to know the mechanical properties of the corroded strands in ...
