The dynamic property of shear-damped laminate plate with viscoelastic material and foam plastic core layers is studied by vibration test. Through the analysis of the dynamic response, it has been proved that the shear-damped plate has better dynamic property, that the vibration energy can be effectively absorbed, and the peak of response can be reduced. According to the test results for different core layers, it is demonstrated that shock absorption of the shear-damped plate can be promoted by adding more layers of viscoelastic material.
