Proc. ASME. ESDA2012, Volume 3: Advanced Composite Materials and Processing; Robotics; Information Management and PLM; Design Engineering, 57-61, July 2–4, 2012
Publisher: American Society of Mechanical Engineers
Paper No: ESDA2012-82549
... Drilling composite materials is one of the primary processes of manufacturing industrial structures. The ultimate goal towards on-line monitoring of composites drilling is in order to produce damage free high quality drilled holes. In the present investigation, the acoustic emission (AE...

Proc. ASME. ESDA2012, Volume 3: Advanced Composite Materials and Processing; Robotics; Information Management and PLM; Design Engineering, 69-74, July 2–4, 2012
Publisher: American Society of Mechanical Engineers
Paper No: ESDA2012-82670
... Drilling is a dynamic process which causes some defects in composite materials such as delamination, fiber pull out and matrix cracking. Because of non-stationary behavior of drilling process, using online method to monitor these damage mechanisms is inevitable. In this paper, acoustic emission...

Proc. ASME. ESDA2004, Volume 1, 565-572, July 19–22, 2004
Publisher: American Society of Mechanical Engineers
Paper No: ESDA2004-58540
... 25 11 2008 The ability to model transient wave propagation in solids and determine the Green’s function plays a major role in improving the reliability of quantitative source characterization of acoustic emission. In this work, the finite element method is employed to determine...
