Analysis on vibration, dynamics, and wave propagation of bio-inspired structural materials and its applications

The vibration, dynamics, and wave propagation of bio-inspired structural (BIS) materials will be investigated in this project. The elastic feature of the tubular materials will be explored based on the boundary integral equation method of 2D elasticity and the initial and subsequent yield surfaces of cellular materials will be detected by finite element simulations and its collapse surface derived analytically. The vibration properties of cellular materials and brick-and-mortar materials will be investigated according to the analytical solution. Further, the dynamic modeling on BIS materials will be conducted and the analytical solution under different loadings will be derived. Based on the analytical solution, the experimental strategy/process will be arranged and the performance of BIS materials will be design. Therefore, thoroughly understating of dynamics and wave propagation of BIS materials will be increased in the analytical and experimental study. In addition, a functional BIS-material bearing installed in a bridge will be analyzed and examined its capability of seismic load reduction analytically and quantitatively.
