Mode selection of guided waves in an elastic steel plate with thick coating layer has been studied here. E€ect of both thick elastic coating and damping of the coating layer on the dispersion and mode shapes has been investigated and modes that are less a€ected by elastic coating and damping have been identi®ed. For modeling the viscoelastic behavior of the coating layer, the standard linear so...

Ultrasonic elasticity imaging enables visualization of soft tissue deformation for medical diagnosis. Our aim is to understand the role of flow-dependent and flow-independent viscoelastic mechanisms in the response of biphasic polymeric media, including biological tissues and hydrogels, to low-frequency forces. Combining the results of confined and unconfined compression experiments on gelatin ...

The nonlinear dynamic response of thin plates made of linear viscoelastic material of fractional derivative type is investigated. The resulting governing equations are three coupled nonlinear fractional partial differential equations in terms of displacements. The solution is achieved using the AEM. According to this method the original equations are converted into three uncoupled linear equati...

To get clear the vibration mechanism of sandwith shell using experiment method, a double-layered plate is designed for sandwich by matching equivalent impedance. Numerical analysis conducted, and In 10Hz-4000Hz, differenceof impedance from should be less than 10%. A new design given plate, which quite simple construction. Then, could applied to conduct series tests influence core material on st...

We evaluated the variability in the amount of protein adsorbed onto the surface of individual wells of an assortment of microtitre plates by use of procedures involving enzyme-protein conjugates. Coefficients of variation in adsorbed protein ranged from 5.2 to 29.5%. Microtitre plates show a distinct "edge effect"; wells at the edges of a plate adsorb more protein than those in the interior, wh...

This study describes a novel fabrication method of a multi-pad paper plate (MP) for transfer and optimisation of enzyme-linked immunosorbent assays (ELISA) on paper. The plate was fabricated using a combination of laser cutting and lamination for rapid and low-cost production of a multi-pad paper plate compatible with a standard 96 well microplate format. The plate was used to transfer a sandwi...

The mechanical response and fracture of metal sandwich panels subjected to multiple impulsive pressure loads (shocks) were investigated for panels with honeycomb and folded plate core constructions. The structural performance of panels with specific core configurations under multiple impulsive pressure loads is quantified by the maximum transverse deflection of the face sheets and the core crus...
