6Effect of fiber orientation in uni-directional glass epoxy laminate using acoustic emission monitoring显示文摘Acoustic emission(AE) can be used for in situ structural health monitoring of the composite laminates. One of the main issues of AE is to characterize different dam-age mechanisms from the detected AE signals. In the present work,pure resin and GFRP composites laminates with different stacking sequences such as 0,90,angle ply[±45 ],cross-ply [0 /90 ] are used to trigger different failure mechanisms when subjected to tensile test with AE monitoring. The study of failure mechanisms is facilitated by the choice of different oriented specimens in which one or two such mechanisms predominate. Range of peak frequencies in each orientation is investi-gated using FFT analysis. Fast Fourier Transform(FFT) enabled calculating the frequency content of each damage mechanism. Randomly selected hits from each range of peak frequencies for the specimens with different orientations subjected to tensile test with AE monitoring are analyzed using short time FFT(STFFT) anal-ysis. STFFT analysis is used to highlight the possible failure mechanism associated with each signal. The predominance of failure modes in each orientation is useful in the study of discrimination of failure modes in composite laminates from AE data.V.Arumugam S.Barath Kumar C.Santulli A.Joseph Stanley 2011Acta Metallurgica Sinica(English Letters)2011,24,5:0
7Ultimate Strength Prediction of Carbon/Epoxy Tensile Specimens from Acoustic Emission Data显示文摘The objective of this paper was to predict the residual strength of post impacted carbon/epoxy composite laminates using an online acoustic emission (AE) monitoring and artificial neural networks (ANN). The laminates were made from eight-layered carbon (in woven mat form) with epoxy as the binding medium by hand lay-up technique and cured at a pressure of 100 kg/cm2 under room temperature using a 30 ton capacity compression molding machine for 24 h. 21 tensile specimens (ASTM D3039 standard) were cut from the cross ply laminates. 16 specimens were subjected to impact load from three different heights using a Fractovis Plus drop impact tester. Both impacted and non-impacted specimens were subjected to uniaxial tension under the acoustic emission monitoring using a 100 kN FIE servo hydraulic universal testing machine. The dominant AE parameters such as counts, energy, duration, rise time and amplitude are recorded during monitoring. Cumulative counts corresponding to the amplitude ranges obtained during the tensile testing are used to train the network. This network can be used to predict the failure load of a similar specimen subjected to uniaxial tension under acoustic emission monitoring for certain percentage of the average failure load.V.Arumugam R.Naren Shankar B.T.N.Sridhar A.Joseph Stanley 2010Journal of Materials Science & Technology2010,26,8:0
8超声波声速测量在奥氏体不锈钢粒度判断中的应用显示文摘超声波声达测量已用于AISI316型不锈钢一般粒度的判断。脉冲反射重叠技术用于超声波传输时间的精确测量。通过金相照片获得与超声波声速有关的粒度主要图像。结果表明利用超声波声速测量预测粒度有较好的互信度等级。与纵波相比较,发现横波关于粒度测量更敏感。发现用声达测量来判断粒度比用裹减测量所获得的粒度更精确。P.palanichamy A.Joseph 王莹 1998无损探伤1998,,3:0
