A cantilever shell with a one-sided clamped boundary condition exhibits five stable configurations (denoted
I, I*, J, L, and S). First, experimental and finite element modal analyses are performed to identify promising candidates for
efficient transitions between these configurations. The structure is then subjected to large-amplitude kinematic excitation.
This allows investigation of nonlinear in-well dynamics, including hardening and softening responses, as well as internal
resonances. Cross-well responses are also examined, and different types of motion are quantified. In the second part of the
study, based on a deeper understanding of the shell’s nonlinear behavior, a procedure for preferable embedding of a Macro
Fiber Composite (MFC) patch is proposed. This enables quantification of both the types of motion and the corresponding
magnitudes of harvested energy.
