EXPERIMENTAL & ANALYTICAL INVESTIGATION OF E GLASS EPOXY CANTILEVER BEAM FOR CRACK IDENTIFICATION

mechanical engineering

In many field like civil, mechanical, naval & aeronautical engineering beams are broadly used. So that crack identification is main issue as due to existence of cracks changes the physical characteristics of a structure. The vibration parameters such as natural frequency, mode shape, stiffness and modal damping affected by presence of crack performance of structure is also affected. This work is to model an inclined crack in a composite material (E Glass Epoxy) cantilever beam and analyze the model using FEA as well as experimental. This proposed method is based on natural frequencies and mode shape of the beam. The using specimen having cracks of different depth and position of FEA results are obtained. By using FFT analyzer experiment is carried out. In this experiment the relationship between the natural frequencies, crack position, crack seriousness has to be studied but the certain relation that to study between crack depth and natural frequency.
