Application of statistical methods for predicting uniaxial compressive strength of limestone rocks using nondestructive tests
Uniaxial compressive strength (UCS) of an intact rock is an important geotechnical parameter for engineering applications. Using standard laboratory tests to determine UCS is a difficult, expensive and time-consuming task. ...
SEPARATION STEEL PARTS WITH DIFFERENTE MICROSTRUCTURE USING BARKHAUSEN NOISE ANALYSIS
Among different nondestructive magnetic methods, barkhausen noise is a new one in evaluation of metallurgical and mechanical properties of ferromagnetic materials such as grain size, hardness and microstructure assessment as well as determination...
NONDESTRUCTIVE EVALUATION OF MECHANICAL PROPERTIES OF DUCTILE CAST IRON PARTS USING EDDY CURRENT SIGNALS
The present research investigates improvement of Eddy Current (EC) technique as a
nondestructive method for measurement of ductile cast iron microstructural and mechanical
characteristics. Six samples of heat treated ductile cast iron...
An investigation into the applicability of Barkhausen noise technique in evaluation of machining properties of high carbon steel parts with different degrees of spheroidization
Capability of Barkhausen noise (BN) technique in evaluation of spheroidizing process and determination of the consequent machining properties were investigated. Samples with different degrees of spheroidization were produced ...
Quality control of precipitation hardened alloy parts via eddy-current nondestructive evaluation
. The quality control of aluminium alloy specimens is an important concern of engineers. Among different methods, non-destructive techniques are faster, cheaper and are able to be used for 100% of specimens. To assess the ability of eddy current as a non-destructive...
Hyperspectral imaging as an effective tool for prediction the moisture content and textural characteristics of roasted pistachio kernels
The objective of this study was to develop calibration models for prediction of moisture content and textural characteristics (fracture force, hardness, apparent modulus of elasticity and compressive energy) of pistachio ...
Reliability and sensitivity of visible liquid penetrant NDT for inspection of welded components
stage of welding procedure. One of the main categories of the defects is surface cracks, which are found by nondestructive testing methods. However, visible liquid
penetrant as a technique to reveal this kind of flaws is broadly used, the method...
