SUMMARY:Monitoring Natural Frequencies of Composite Structures as a Means t
 o Detect Defects
DESCRIPTION:Lecturer:Shahar Penias\n Faculty:Department of Aerospace Engine
 ering\n Institute:Technion – Israel Institute of Technology\n Location:C
 lassroom 165\, ground floor\, Library\, Aerospace Eng.\n Zoom: \n Abstract
 : \n Details: \n Composite materials take a large part in the aerospace in
 dustry\, and keep getting ever more dominant in air-borne structures. Ther
 e is at least one field in which composite materials had not yet become as
  advanced as metals\, and that is NDI. In this work we try to find a solut
 ion for the problem of interlaminar delaminations in laminate composite ma
 terials. The aim for this work is developing an on-site (In-situ (method t
 o be used in order to detect and evaluate a delamination.\nThe method we h
 ave chosen is a modal analysis of a beam\, in order to detect a change in 
 its natural frequencies\, which will indicate the presence of delamination
 s. In order to achieve this goal a large amount of numerical analysis alon
 gside vibration experiments were performed. The end result is a "recipe" f
 or detecting delaminations using a minimal amount of sensors and equipment
 .
