The strain-hardening behaviour of a tempered martensitic iron-chromium-carbon model was examined in terms of dislocation mechanics. Tensile tests of this body-centered cubic alloy were carried out from 77 up to 293 K. A specific relationship between the fl ...
It has been known for more than 150 years that action effects in bridges due to traffic action are higher than it has to be expected for purely static loads. In the design of road bridges, this difference is considered by multiplying static traffic loads w ...
A detailed study of the strain-hardening on a Fe-9Cr-0.1C tempered martensitic model alloy has been undertaken in the temperature range of 77-343 K. The true stress-true strain curves were calculated from tensile test data. In the framework of a phenomenol ...
Reinforced concrete slabs supported on columns fail by punching when a conical plug of concrete perforates the slab above the column. This failure has been mostly investigated experimentally, so what can numerical simulation contribute to understand this p ...
This paper provides a review of theoretical and experimental research to date on the constrained steady state solidification of dilute binary alloy matrix composites. Steady state solidification can be experimentally observed in composites which contain a ...
The influence of plastic strains in the longitudinal reinforcement in presence of high shear forces in beams and slabs without stirrups was investigated performing a series of tests of eight ordinary reinforced concrete beams 8.4 meters long with 0.79% rei ...
Modeling of the constitutive behavior was undertaken for Fe- Cr-C tempered martensitic alloys. Tensile tests were carried out at room temperature and constant nominal strain rate. In order to obtain a fully martensitic structure with different prior austen ...
In an effort to better understand the plasticity of tempered martensitic steels, uniaxial tension and compression tests were carried out. The temperature dependence of both the yield stress and the post-yield stress behavior were compared, and it was shown ...
The present workshop dealt both theoretically and experimentally with issues of primary damage and irradiation induced defect evolution, helium and other impurities, dislocation-defect interactions, deformation to large plastic strains and fracture. It was ...
We perform detailed finite element simulations of impact of metallic plates by spherical particles over a range of impact angles and speeds with a view to develop an insight into the fundamental mechanisms underlying solid-particle erosion. The particular ...
