IJREI_Vibration analysis of a cantilever beam with crack depth and crack location effects

Downloads: 111 Avg Rating: 0.00 By: Mr Editor Ijrei in 2017.
Alloy beams and beam like elements are principal constituents of many structures and widely used in high speed machinery,
aircraft and light weight structures. Crack is a damage that often occurs on members of structures and may cause serious
failures of structures. In this research, the natural frequency of a cracked cantilever beam is investigated by finite element
method by using of ANSYS program with different crack depth and location effect. The beam material studied is aluminum
alloy, titanium alloy, copper alloy and magnesium alloy. A comparison is made of these alloys and concludes optimized
result between them. The increase of the beam length result in a decrease in the natural frequencies of the composite beam
and also shows that an increase of the depth of cracks leads to a decrease in the value of natural frequencies.
