研究了非晶态碳材料板碰撞下的一维应变动态响应 .利用在碰撞材料样品和非晶态碳样品上的石英压力传感器测量了样品中的应力历史和冲击波速度 .对试验测得的速度及应力历史进行了分析处理 .在 4 0GPa的冲击条件下 ,非晶态碳材料的冲击响应波形是简单稳定的 ,其一维应变条件下为非线性弹性响应 ,在试验冲击应力范围内没有发现非弹性变形 .试验数据显示材料的Hugoniot曲线是上凸的 ,与熔硅材料相似 .试验结果表明非晶态碳材料冲击状态下内部传播的不是一个冲击波而是一个压缩波
The dynamic response of one-dimensional strain under amorphous carbon plate collision was investigated. The stress history and shock wave velocity in the sample were measured by quartz pressure sensor on the impact material and amorphous carbon specimen. The measured velocity And stress history were analyzed and treated.The impulse response of amorphous carbon material was simple and stable under the impact condition of 40GPa, and its nonlinear elastic response under one-dimensional strain was not found in the range of experimental impact stress Non-elastic deformation.The experimental data show that the Hugoniot curve of the material is convex, similar to the fused silicon material.The experimental results show that the non-crystalline carbon material propagates in the shock state instead of a shock wave but a compressional wave
