โœฆ Synopsis

The transient response of a laminated beam is investigated . An analytical model taking into account the interface shear deformation is presented . Delamination in ply interface is studied by calculating the time dependent strain energy release rate for the interface crack . Factors like the time dependence, the transient loading pulse shape and the adhesive material are found to have important effects on the shear failure mode at the interface and hence on the impact resistance of the laminated structures .

In addition to the deflection due to pure bending in a beam, there is a shear force in all cases of non-uniform bending and a further deflection, due to shear stresses.~ This additional shear deflection usually is assumed to be negligible and is not considered in computing the total deflection of a
