| 摘要 | The layer-by-layer viscoelastic sandwich nanocomposites have been widely used as high-efficient shock absorbers in nano-engineering since its excellent performance in vibration isolation. Such structure often works in thermoelastic coupling condition, and a thorough and comprehensive investigation on its structural dynamic responses is imperatively needed to achieve the goal of improving heat isolation and avoiding unwanted vibration. In this work, an analytical study is conducted to investigate the structural dynamic responses of layer-by-layer viscoelastic sandwich nanocomposites based on nonlocal thermo-viscoelasticity theory. The two lateral bounding surfaces of the structure are subjected to the time-varying symmetric thermal shock loadings. It is assumed that thermal contact resistance and elastic wave impedance at the interface are zero with idealized adhesion. Governing equations of each homogeneous isotropic viscoelastic layer are derived and solved by a semi-analytical technique via Laplace transformation. The achieved results show that the heat isolation will be maximally improved and harmful thermal induced stress is lowered to some extent if properly selecting nonlocal parameters and material constants ratios. |
