The aim
of this paper is to discuss various techniques used by various researchers
for vibration based crack detection in cracked composite structures. In
aeronautical, mechanical and civil engineering fields various structural
systems are likely to damage and deterioration during their working period.
So it is very important to find damage and deterioration in structural member
by an effective and reliable methodology. Interest in various damage
detection methods has considerably increased in last few decades. A local
flexibility is introduced in structural member due to the presence of crack
that would affect the vibration response of structure. Due to the presence of
crack there is reduction in stiffness of structure and increase in damping of
the structure. Since there are changes in physical properties there are
reductions in natural frequencies and deviation in mode shapes. Therefore by
measuring the vibration parameters it is possible to predict crack depth and
crack location in structural member. In this paper effect of various
parameters like crack depth, crack location on natural frequency of beam is
studied.Presence of crack in a beam decreases the natural frequency which is
more pronounced when the crack is near the fixed support and the crack depth
is more. Mr. Kadam Satish P | Dr. Kachare P.S."A Review on Detection of
