本文提出了一种能够巧妙控制裂纹驱动力的加压泡罩试验加载方法。对利用这种加载方法测量薄膜/衬底界面的粘附能进行了理论研究。考虑的问题包括求解圆形泡罩下的精确体积和储存在薄泡罩膜中的弹性应变能，确定浇注的有色液体作为系统的外力所做的功和储存在压缩空气中的弹性应变能。最后提出了一种新的能量释放率公式。本文所做的工作与已有的工作进行了比较。
In this paper, a new loading method able to subtly control the crack driving force for pressurized blister test was proposed. A theoretical study of the adhesion energy measurement for film/substrate interface using this loading method was presented. Problems considered include solving the exact volume under a circular blister and the elastic strain energy stored in a thin blistering film, determining the work done by the poured colored liquid as external force to the system and the elastic strain energy stored in the compressed air. A new formula of energy release rate was finally presented. A comparison between the work presented here and the existing work was made.
