论文摘要
Afferrante and Carbone（2016）在一种对粘弹性底物的弹性胶带剥离的优雅而有趣的理论中，发现，与经典的弹性肯德尔的理论相反，在稳态剥离中，稳态剥离的负载可能是稳态剥离的载荷，在稳态剥离中可能是很大的，在稳定状态下，在低调的角度上，他们称呼“ peeling of peeling -where sell of peel'peel'peeling'peeling'peeling'peeling''实际上，这里显示的是，这是在临界速度接近肯德尔方程的弹性术语与粘弹性耗散平衡的。令人惊讶的是，这似乎导致韧性提高高于在无限粘弹性体中非常大的裂缝中观察到的极限值，甚至可能考虑到越来越多的限制所传播的应力。肯德尔的实验反过来考虑了粘弹性磁带（而不是基板），他的粘弹性发现似乎导致了更简单的图像。 Adrante-Carbone理论认为粘弹性效应是一种开关机制，因为对于剥离的很大角度，它几乎微不足道，而仅低于一定阈值，这种“ Ultratough”剥离似乎出现了。实验和/或数值验证将是最有用的。
In an elegant and interesting theory of ultratough peeling of an elastic tape from a viscoelastic substrate, Afferrante and Carbone (2016) find that, in contrast to the classic elastic Kendall's theory, there are conditions for which the load for steady state peeling could be arbitrarily large in steady state peeling, at low angles of peeling - what they call "ultratough" peeling. It is here shown in fact that this occurs near critical speeds where the elastic energy term of Kendall's equation is balanced by the viscoelastic dissipation. Surprisingly, this seems to lead to toughness enhancement higher than the limit value observed in a very large crack in a infinite viscoelastic body, possibly even considering a limit on the stress transmitted. Kendall's experiments in turn had considered viscoelastic tapes (rather than substrates), and his viscoelastic findinds seem to lead to a much simpler picture. The Afferrante-Carbone theory suggests the viscoelastic effect to be an on-off mechanism, since for large angles of peeling it is almost insignificant, while only below a certain threshold, this "ultratough" peeling seems to appear. Experimental and/or numerical verification would be most useful.
