Finite element modeling and analysis of a debonded smart beam in actuation

Stress, strain and displacement-based analysis of smart beam with debonding under actuation have been carried out. In this regard variational formulation based finite element modeling of a smart beam under actuation with debonding on the top and a bottom piezo layer has been developed. To know the p...
