Abstract: 

This paper describes a strategy for predicting the extent of internal damage in a laminated composite structure, when subjected to low velocity impact. The success of the predictions is validated by experiments. Delamination as a result of low-velocity impact loading is a major cause of failure in fiber-reinforced composites. The delamination size was obtained when the' transverse shear force rate reached interlaminar fracture toughness. Post-impact examination of damage is carried out by visual inspection. The impact loading is treated as an equivalent static loading by assuming the impactor to be semi-spherical and the contact to obey Hertzian law.

An analytic solution which includes both transverse shear and contact deformation is presented. A First shear deformation theory is employed and solutions for the loads, displacements and strains are obtained using Fourier series expansions. Subsequently, the Tresca criterion is used to detect the zones of failure. It is demonstrated that for given specimens lay-up the materials subjected to impact load whit low rang of energy suffer damage according to the magnitude of the both impactor mass and velocity.
