Numerical and analytical study on low velocity impact response of functionally graded carbon nanotube reinforced composite beams

In this work response of functionally graded carbon nanotube reinforced composite beam subjected to the action of an impacting mass is investigated analytically and numerically. Timoshenko beam theory is used to estimate the kinematics of the beam. Material properties of the composite are obtained using a refined rule of mixture. However for numerical model surface to surface has been used. The beam cross section considered uniform and the impactor assume a Steel made ball. Numerical has reasonable agreement compare with analytical model and results show that the Fem model can predict the beam behavior with very good agreement
