Comparison of Analytical and Numerical Methods for Delaminated Composite Beams

Abstract

In this thesis, the effects of delamination length on the deformations, stresses, stress intensity factors for composite beams are analyzed using Ansys software. The composite materials considered are E Glass Fiber, S2 Glass and Aramid Fiber. Static and Fracture analyses are done on the composite beam by varying number of layers 3, 5 & 7. By this the effect of delamination is determined. Numerical calculations are also done to compare with that of analytical results.
