Flexural Vibration Band Gap Characteristic of Double Periodic Structure Beams

Band-Gap Structure of the Spectrum of Periodic Maxwell Operators

We investigate the band-gap structure of some second-order differential operators associated with the propagation of waves in periodic two-component media. Particularly, the operator associated with the Maxwell equations with position-dependent dielectric constant e(x), x e R 3, is considered. The medium is assumed to consist of two components: the background, where e(x)= eh, and the embedded c...

Coupling of flexural and longitudinal wave motion in a periodic structure with asymmetrically arranged transverse beams

A Semi-analytical Solution for Flexural Vibration of Micro Beams Based on the Strain Gradient Theory

In this paper, the flexural free vibrations of three dimensional micro beams are investigated based on strain gradient theory. The most general form of the strain gradient theory which contains five higher-order material constants has been applied to the micro beam to take the small-scale effects into account. Having considered the Euler-Bernoulli beam model, governing equations of motion are w...

Flexural Behaviour of RCC Beams

Concrete is the material which is rapidly used in various conditions to sustain the compression loads and the corresponding bending and shear stress due to the applied compressive loads. The major drawback in concrete is that it is poor in tension though it is very efficient in compression. Hence to overcome this major drawback the concrete must be reinforced such that to make a homogeneous sub...

Flexural Behavior of Reinforced HPFRCC Beams

High Performance Fiber Reinforced Cementitious Composite (HPFRCC) materials exhibit strain hardening behavior with multiple cracking under tensile loading. In this paper, experimental and parametric studies are performed to assess the influence of using HPFRCC material instead of normal concrete in reinforced concrete beams. After calibrating the experimental results, the analytical results inc...
