This paper presents a summary of the new semi-analytical integration method presented in [10] for von Mises elastoplasticity model with combined linear isotropic-kinematic hardening within a small deformation range. Solutions for the case of constant strain rate and constant stress rate assumptions are also presented. Furthemore, it is shown how the general solution reduces to the particular ca...

The process of laser beam transformation hardening is principally controlled by two independent parameters, the absorbed laser power on a given area and the interaction time. These parameters can be transformed into two functional parameters: the maximum surface temperature and the hardening depth. It has been proved that with a constant hardening depth the results (hardness. residual stress. e...

Expansion of the offshore wind industry in seismically active areas has raised concerns regarding structural integrity turbines under earthquake loading. This paper details a 3D finite element study to investigate behaviour structure, and particular transition piece (TP), seismic loads. The work focuses on equivalent grouted connection TP-less designs, selected as promising design solutions for...

Mechanochemical activation processes effect on rheological fresh characteristics. Effect mechanochemical mechanism mechanical properties grout. In this research, a (MG) grout is adopted to activate slag, fly ash, hydroxide, silicate b...

This paper presents a new formulation of a well known double hardening model often referred to as the Hardening Soil model. As an alternative to the existing Hardening Soil model’s Mohr-Coulomb failure surface, the new formulation allows for the incorporation of smooth failure surfaces, such as the failure surface proposed by Matsuoka & Nakai or that proposed by Lade & Duncan. Although the inco...

In this paper, we propose an aspect-oriented language, called SHL (Security Hardening Language), for specifying systematically the security hardening solutions. This language constitutes our new achievement towards developing our security hardening framework. SHL allows the description and specification of security hardening plans and patterns that are used to harden systematically security int...

C ommercially available fiberbased reinforcement for concrete is made of carbon, aramid, or glass filament fibers impregnated in a resin. Some aramid fiber reinforcement consists of aramid filaments without a resin matrix. For general applications, the most important feature of fiber-based reinforcement is its resistance to corrosion, which makes it ideal for reinforcing concrete exposed to hig...

Several studies on different techniques can be found retrofitting existing unreinforced masonry (URM) walls using varieties of materials ranging from reinforced plaster, grout and epoxy injectio...
