Study of the Frictional Surface Damage Using Acoustic Emission Method
In this study, the change at rubbing surfaces has been investigated experimentally using an acoustic emission signal monitoring system. A steel ring is slipped on the surface of a metallic sheet to simulate frictional conditions. The mechanical disturbances caused by the movement of the ring produce stress waves propagating along the sheet surface. The out of plane displacement of the sheet su...
متن کاملHigh-temperature acoustic emission tests using lithium niobate piezocomposite transducers
Acoustic emission (AE) analysis is used for testing materials in structural components and machinery. Acoustic emission frequently consists of ultrasound in the frequency range 100 kHz to 1 MHz, generated either from growing cracks or from mechanical failure in rotating machinery. In the case of crack growth, individual AE events correspond to the release of elastic energy as the crack grows st...
متن کاملfailure behavior assessing of wood strands under tensile loading using acoustic emission technique
with the aim of identifying failure mechanism in oriented strand boards, failure behavior of wood strands under tensile load was investigated using acoustic emission technique. resinated and unresinated strands were arranged at top, middle and bottom section of the board before pressing. tensile and acoustic emission tests were performed simultaneously on treated and control samples. using tens...
متن کاملCharacteristics of the acoustic emission during horizontal single grit scratch tests: Part 1 characteristics and identification
Material process in grinding involves three phenomena namely: rubbing, ploughing and cutting. Rubbing and ploughing, which usually occur before or after cutting, essentially mean the energy is being applied less efficiently in terms of material removal. It is therefore important to identify the effects of these different phenomena experienced during grinding. To identify the different phenomena...
متن کاملCharacteristics of the acoustic emission during horizontal single grit scratch tests: Part 2 classification and grinding tests
The second part of this work follows on the work carried out in Part 1 where the investigations were made between the grinding phenomena: cutting, ploughing and rubbing. The demarcation between each of the phenomenon was identified from Acoustic Emission (AE) signals being converted to the frequency-time domains using Short-Time Fourier Transforms (STFTs). Other digital signal processing techni...
