Non-destructive evaluation method employing dielectric electrostatic ultrasonic transducers [PDF]
An acoustic nonlinearity parameter (.beta.) measurement method and system for Non-Destructive Evaluation (NDE) of materials and structural members novelly employs a loosely mounted dielectric electrostatic ultrasonic transducer (DEUT) to receive and ...

Automated analysis of non destructive evaluation data
Interpretation of NDE data can be unreliable and difficult due to the complex interaction between the instrument, object under inspection and noise and uncertainties about the system or data.

Investigation of co-travelling solitary wave collisions in a granular chain [PDF]
We present investigations into the collision of co-travelling solitary waves in a granular chain. Impulses are injected into the system by means of a piezo stack and the results are compared to a numerical model of discrete masses connected by non-linear

Carbon nanomaterial‐reinforced epoxy composites exhibit pronounced piezoresistive behavior, enabling intrinsic damage sensing under cyclic and fatigue loading. This review critically compares carbon nanotube and graphene systems, correlating filler content, percolation threshold, and gauge factor with sensing stability and damage evolution.

Quantitative non-destructive evaluation of porous composite materials based on ultrasonic wave propagation [PDF]
Porosity in composite media using ultrasonic waves is characterized. The derivation of local approximations to the Kramers-Kronig relations are presented and it is shown that they may also be applicable to systems that could conceivably exhibit ...

Non-destructive evaluation of composite materials using ultrasound [PDF]
Investigation of the nondestructive evaluation of advanced composite-laminates is summarized. Indices derived from the measurement of fundamental acoustic parameters are used in order to quantitatively estimate the local material properties of the ...

Handbook of Establishing and Maintaining Oxygen‐Free Atmospheres
This study presents a practical framework for creating oxygen‐free atmospheres at ambient pressure using silane‐doped inert gases. The results show that ultra‐low oxygen levels and strongly reduced water content can be achieved through controlled silane dosing, drying systems, and sensor monitoring.

Hot corrosion characteristics of SrCeO3 as thermal barrier coating material
This study investigates the thermal barrier and hot corrosion characteristics of SrCeO3, a perovskite-structured material, synthesized via the solid-state method using SrCO3 and CeO2 as precursors. The crystal structure was confirmed by x-ray diffraction
