One challenge for geotechnical centrifuge testing of soil–structure interaction problems is the reliable measurement induced structural strains/forces. This paper presents a novel application fibre Bragg grating (FBG) sensors strain within tests. FBG have several advantages testing, in particular their small size and minimal self-weight. gives an overview recently developed installation calibra...

Accepted: 31.12.2014 In this study, analysed using finite element method (FEM) of biomechanical behaviours of human femur model under the different loads. Geomagic and Soldiworks program were used for 3D model human of femur model, and Ansysworkbench was used for finite element analysis (FEA). Compression, tension, bending and torsional loading were applied to 3D human femur model. Femur bone w...

An elastic analysis is presented for the tensile stretching and bending of a plate containing a surface crack penetrating part-through the thickness, Fig. 1. The treatment is approximate, in that the two-dimensional generalized plane stress and KirchhoffPoisson plate bending theories are employed, with the part-through cracked section represented as a continuous line spring. The spring has both...

Statement o f p rob l em . Despite their mobility differences under occlusal loads, a natural tooth and an implant are often used together to support fixed prostheses. In some situations, tooth/implant-supported partial prostheses include cantilever extensions, especially in the posterior region where the bone is inadequate for placement of an additional implant. Purpose . In this study, engine...

Carbon nanotubes (CNTs) are highly sensitive towards dipole molecules, mechanical loads, interfacial contacts, chemical modifications and temperature fluctuations. Their applications are currently limited to electron-field-emission and gas-sensing devices. In fact, CNTs can also be used as strain-sensing elements; for example, variations in CNT resistance with bending strain have been character...

In this paper, collapse behavior of simple and reinforced thin-walled channel- section beams, subjected to three- point bending, is investigated. Many simple channel- section beams of different geometry and some reinforced ones were tested, and their strengths after collapse were obtained thoroughly. Since the available theories in this area are complicated and little attention has been paid to...

The fatigue life of tubular joints commonly found in offshore industry is not only dependent on the value of Hot-spot stress (HSS), but is also significantly influenced by the through-the-thickness stress distribution characterized by the degree of bending (DoB). The determination of DoB values in a tubular joint is essential for improving the accuracy of fatigue life estimation using the stres...

A class of planar, pin-jointed truss structures based on the ancient Kagome basket weave pattern with exceptional characteristics for actuation has been identified. Its in-plane stiffness is isotropic and has optimal weight among planar trusses for specified stiffness or strength. The version with welded joints resists plastic yielding and buckling, while storing minimal energy upon truss bendi...

Theoretical studies have indicated that truss core panels with a tetragonal topology support bending and compression loads at lower weight than competing concepts. The goal of this study is to validate this prediction by implementing an experimental protocol that probes the key mechanical characteristics while addressing node eccentricity and structural robustness. For this purpose, panels have...

As the wind turbine size has been increasing and their mechanical components are built lighter, the reduction of the structural loads becomes a very important task of wind turbine control in addition to maximum wind power capture. In this paper, we present a separate set of collective and individual pitch control algorithms. Both pitch control algorithms use the LQR control technique with integ...
