Abstract
En 中文
Although it is acknowledged that using periodically heterogeneous film can improve adhesion properties without interface modification, there is still a lack of comprehensive research in the existing literature that specifically investigates the behavior of peeling of such film from rigid substrate at arbitrary peeling angle. To this end, two theoretical models, an accurate and an approximate model, for the peeling of periodically heterogeneous film at arbitrary peeling angle are proposed in this study. The primary focus of the present study is on examining the peeling behavior of such film, with special attention given to the impact of peeling angle on the peeling behavior. Our analysis revealed two unknown peeling behaviors. Firstly, the use of periodically heterogeneous film not only enhance the adhesion performance of its stiff section, but also weakens the adhesion performance of its compliant section. Secondly, the enhancing ratio of adhesion performance does not remain constant, nor does it exhibit a monotonically increasing function with the peeling angle. Instead, it initially increases and then decreases as the peeling angle increases. The weakening ratio of adhesion performance with respect to the peeling angle is similar to that of the enhancing ratio. The influence of several parameters, including the bending stiffness ratio, adhesion energy, bending stiffness of the compliant section, period length of the periodically heterogeneous film, and length fraction of the stiff section, on the peeling of periodically heterogeneous film at arbitrary peeling angle are also studied. Based on the accurate theory, a formula for calculating the peeling force of homogeneous film is also derived. The calculated results using the proposed formula are in excellent agreement with the classical Kendall theory.
