Experimental Study on Cyclic Behaviors and Restoring Force Characteristics of Concrete Filled Steel Tube Columns Using Ultra-High Strength Steel
H-SA700 is a type of new ultra-high-strength structural steel that is more environmentally friendly and more suitable for mass production than conventional high-strength steel. The objective of this paper is to contribute to the practical application of CF ...
International Association of Earthquake Engineering2017Ductility, recovery and strain rate dependency of an acrylic structural adhesive
Thomas Keller, Anastasios Vassilopoulos, Myrsini Angelidi
The ductility and time-dependent recovery of a ductile acrylic adhesive were investigated in this work. The quasi-static true tensile and compressive strain behaviors were examined at different strain rates, taking large deformations into account. Yield st ...
Elsevier2017The flow stress evolution and grain refinement mechanisms during hot deformation of Al-Mg alloy
In this study, the hot deformation behavior of an Al-1% Mg alloy with very coarse initial grain size was investigated in terms of flow stress evolution and grain refinement mechanism. The large grain size was employed to study the traditional continuous dy ...
2017Deformation behavior of nanoporous polycrystalline silver layers sintered by low temperature bonding: experiment and simulation
Integrated circuit packaging technology has become a prime design consideration for the develop-ment of electronic system concepts. One key issue is the bonding layer between chip and substrate. Currently, high-lead solder materials are being used, which a ...
EPFL2016Brittle versus ductile deformation as the main control of the deep fluid circulation in oceanic crust
The brittle to ductile transition may strongly influence hydraulic properties of rocks at the depth and temperature ranges that hydrothermal fluids circulate. To examine this transition in the context of the oceanic crust, we conducted a series of deformat ...
American Geophysical Union2015Tensile elongation of unidirectional or laminated composites combining a brittle reinforcement with a ductile strain and strain-rate hardening matrix
Andreas Mortensen, Amaël Maximilien Cohades
We use the long-wavelength model of Hutchinson and Neale (1977) and Ghosh (1977) to estimate the uniform tensile elongation of two-phase composites deforming quasistatically according to the equistrain rule of mixtures, in which one phase is ductile while ...
Elsevier2014Modelling shear–flexure interaction in equivalent frame models of slender reinforced concrete walls
Katrin Beyer, Panagiotis Mergos
Quasi-static cyclic tests on reinforced concrete (RC) walls have shown that shear deformations can constitute a significant ratio of the total deformations when the wall is loaded beyond the elastic regime. For slender RC walls that form a stable flexural ...
2014Correlation between ferrite grain size, microstructure and tensile properties of 0.17wt% carbon steel with traces of microalloying elements
Five different grain sizes are produced in 0.17 wt% carbon steel using varying rates of cooling from austenitization temperatures. Controlled furnace cooling from 1100 °C and 950 °C produces coarse ferrite grains of 40 µm and 32 µm diameter, respectively, ...
Elsevier2014An analysis of the tensile elongation to failure of laminated metal composites in the presence of strain-rate hardening
Andreas Mortensen, Arda Cetin, Cécile Bernardi
We extend the analysis of Hutchinson and Neale (Hutchinson JW, Neale KW. Acta Metall 1977;25:839) and Ghosh (Ghosh AK. Acta Metall 1977;25:1413) predicting the tensile elongation to failure of strain-rate-dependent plastic materials to two-phase composites ...
Elsevier2012Thermally activated plastic flow in the presence of multiple obstacle types
The rate- and temperature-dependent plastic flow in a material containing two types of thermally activatable obstacles to dislocation motion is studied both numerically and theoretically in a regime of relative obstacle densities for which the zero-tempera ...
