Abstract

The dynamic instability analysis of a simply supported variable angle tow (VAT) composite with delamination around a cutout subjected to periodic axial compression load is investigated. The governing equations of motion for the VAT plate are derived based on first-order shear deformation theory and solved using finite element method. The equations of motion contain time periodic coefficients and their stability is determined using the Bolotin’s approach. A parametric study is carried out to analyze the effect of linearly varying fiber orientation angle on the dynamic instability of VAT laminate with delamination around a circular cutout.
