摘要

摘要: 本文采用脉冲激光引发不同材料间界面脱粘的方法,并结合有限元方法对上述脱粘过程进行数值模拟,从而决定界面的拉伸强度。对铜与碳化硅间的界面强度进行了测定,结果表明该界面的拉伸强度为8.36GPa.

Abstract: Alaser spallation experiment technique is used to measure the interface tension strength of Cu/SiC laminate materials. The critical stress amplitude is determined from a computer simulation of the process. It is found that the interface tension strength ranges from 8.19 to 8.56GPa, and the average streng this 8.36 GPa. In the case of Si/SiC, the results given by the paper are in good agreement with the results obtained by Gupta.
