A theoretical method is presented to analyse the low-velocity impact dynamics of a system which consists of a laminated beam and multiple impactor masses. The contact forces between the beam and the impactors are treated as the internal forces of the system. The beam displacement field is defined using a higher-order shear deformation theory and the interaction between the beam and the impactor masses...
A numerical method is presented to evaluate the response of a laminated stepped beam under a transverse low velocity impact. The impactor and the laminated beam are considered as a single system and thus the impact force becomes the internal force of the system. The energies associated with each span of the beam and the impactor mass are derived in the form of a higher order shear deformation theory...
