A nonlinearity evaluation based crack location identification for cantilever beam-like structures using different excitation force levels

Nonlinear characteristics may arise in its forced responses in vibrating structures with inherent nonlinearity. A breathing crack can manifest itself as a structural nonlinearity in cantilever beam-like structures, and its influence on nonlinear effects can not be negligible. Then, measuring the changes of nonlinearity severity of forced responses is an alternative means to detect the cracks in ca...
