In order to evaluate the stress state and working performance of a rigid frame bridge after reconstruction extension, load test transverse distribution were carried out. Static is at each section main beam under action partial medium load. Dynamic used inherent fundamental frequency, damping ratio impact coefficient through pulsation sports car test. The results show that first vibration mainly...

In this paper, an improved refined shear and normal deformation theory is used in order to investigate the vibration behavior of functionally graded rectangular plates. theory, displacements various points plate are assumed be due in-plane middle plane transverse displacement. Transverse displacement divided into three parts: bending, shear, thickness stretching. Using Airy stress function, cor...

An efficient C0 continuous two dimensional (2D) finite element (FE) model is developed based on a refined higher order shear deformation theory (RHSDT) for the static analysis of soft core sandwich plate having imperfections at the layer interfaces. In this (RHSDT) theory, the in-plane displacement field for the face sheets and the core is obtained by superposing a globally varying cubic displa...

The continuous rigid frame bridge of Jiagai River Bridge is (100 + 192 100) m, with a main span 192m, which will break the historical record 176m Chaoyang Jialing and become largest single track railway in China. has characteristics large load, poor stability high prestress requirements. temperature difference sunlight produce deformation emperature stress concrete box girder bridge, affect lin...

Determination of regional ventricular wall stress would allow quantification of both regional contractile state and its interplay with global function. Current methods for quantifying regional stress include mathematical modelling and measurements with strain gauges. Both methods are difficult to validate. We hypothesized that transverse stiffness (i.e., the ratio of indentation stress to strai...

Experimental results of a modified micromachined microelectromechanical systems (MEMS) mirror for substantial enhancement of the transverse laser scanning performance of endoscopic optical coherence tomography (EOCT) are presented. Image distortion due to buckling of MEMS mirror in our previous designs was analyzed and found to be attributed to excessive internal stress of the transverse bimorp...

In this paper, we show that a simple generalization of the holographic axion model can realize spontaneous breaking translational symmetry by considering special gauge-axion higher derivative term. The finite real part and imaginary stress tensor imply dual boundary system is viscoelastic solid. By calculating quasi-normal modes making comparison with predictions from elasticity theory, verify ...

The web of plate girders in bridges are usually reinforced by welded transverse stiffeners in order to improve their shear capacity.Due to problems associated with field welding and fatigue, welded stiffeners are not suitable for retrofitting existing bridges. Bolted stiffeners are a practical alternative for strengthening girders that are expected to experience shear stress in excess of their ...

Lateral constriction (transverse elastic constraint) of rod controls its apparent (longitudinal) stiffness and can even make it negative. (The total energy system + device remains positive.) The depends upon moduli the material modulus relating lateral normal stress strain components. Apparent negative arrest wave propagation along rod. This opens a way to design hybrid materials consisting sti...
