Analytical modeling and finite element simulation of multiple delamination for a composite beam

Abstract

This study concentrates on analytical modelling and simulation of multiple delamination for a composite beam. A detailed simulation of single, double and triple delamination has been studied by varying delamination ratio and location together with harmonic response of the beam. The works done by other researchers have been studied and presented. Matlab script file used to detect mode shapes and natural frequencies of the composite beam. The Euller-Bernulli beam is presented as beam modeling technique for analytical modeling of normal and delaminated cantilever beam depending on previous models. The simulation software used in this research is Ansys mechanical apdl. The finding of this study shows that delamination can affect the natural frequencies and mode shapes of composite beam.
