Dynamic Behavior of Laminates with Ply Lay-up in Various Directions
几种铺层方向复合材料层合板的动态特性试验研究

Cantilever beam specimens made of laminates with ply lay-up in are subjected to free vibration and resonance tests. From these tests, it is found that the coefficients of decrement are consistant; and the fundmental frequencies are also consistant and basically agree with those computed by theoretical approach.
