Abstract
The response of a cantilever beam, represented as a non-linear nonhomogeneous system is determined for pulse loads of the form of a stepfunction and a triangular pulse of finite duration. The non-linearity of the beam arises from a non-linear stress-strain relation and the not linearized curvature. The system exhibits a softening characteristic and is approximately solved by a one-term solution. The response amplitude as well as the period are increased due to the non-linearities of the system. Various cases of variable mass distribution and stiffness have been evaluated.
