In the present study, numerical analysis of concrete columns wrapped with different composite materials is conducted. Different fibre reinforced plastic sheets such as CFRP, BFRP, HFRP, AFRP, GFRP and steel wrapping are taken into consideration. A cylindrical specimen representing a short column modelled Total deformation, Directional deformation Equivalent stresses in core shell were obtained ...

Non-geometric string backgrounds were proposed to be related to a nonassociative deformation of the space-time geometry. In the flux formulation of double field theory (DFT), the structure of mathematically possible non-associative deformations is analyzed in detail. It is argued that on-shell there should not be any violation of associativity in the effective DFT action. For imposing either th...

Elastic anisotropy is present where the speed of a seismic wave depends on its direction. In Earth's mantle, elastic anisotropy is induced by minerals that are preferentially oriented in a directional flow or deformation. Earthquakes generate two seismic wave types: compressional (P) and shear (S) waves, whose coupling in anisotropic rocks leads to scattering, birefringence, and waves with hybr...

Abstract: This paper is concerned with a shape optimization problem of a viscoelastic body in unilateral dynamic contact with a rigid foundation. The contact with Coulomb friction is assumed to occur at a portion of the boundary of the body. The nonpenetration condition is described in terms of velocities. The thermal deformation is taken into account. Using the material derivative method as we...

Ideal strength, which can be defined as the stress necessary to induce permanent deformation in a material without prior imperfections, is one of the important materials characterizations. In this study we calculate the ideal pure shear and simple shear strengths of fcc (Al, Cu, Ni, Ag) and bcc (Fe, Mo, W) metals in their common slip systems using density functional theory. We find the critical...

Fuzzy functional dependency (FFD) is a kind of semantic knowledge and can be discovered from a large volume of business data. Sectional FFD and Attribute FFD are discussed so as to reflect semantics of the business world and express useful information that is natural for people to comprehend. The experimental results on an insurance data set show that the proposed method can extract knowledge e...

Electroactive polymers have been studied for artificial muscle applications in last decades. One of the EAP materials, 3M VHB acrylic tapes, have shown been outstanding electromechanical coupling performance. The scope of this study is to understand the electromechanical properties of VHB acrylic material. In addition, the research explores new practical designs of soft actuators. The basic des...

In this thesis I address the topic of anisotropy – the directional dependence of physical properties of rocks – from two complementary angles: I use seismic anisotropy to detect deformation in the mantle, and I demonstrate the importance of accounting for rheological anisotropy in mantle flow models. The observations of seismic anisotropy in the Earth’s interior allow geophysicists to probe the...
