金属橡胶型可拉伸电子系统中的界面分层导致早期失效。本文报道了金属橡胶界面的调查，通过原位扫描电子显微镜成像的进行分层前的90度剥离试验的橡胶对铜样品。结果表明，50 μ m左右的纤维在成形、伸长和断裂过程中消耗的能量是分离功的主要部分。实验的特点和建模使用内聚区丰富的有限元模型。(C)2010 Acta Materialia Inc.由爱思唯尔有限公司出版。保留所有权利。
Interface delamination in metal-rubber-type stretchable electronic systems leads to early failure. This paper reports an investigation of metal rubber interfaces through in situ scanning electron microscopy imaging of the progressing delamination front of 90 degrees peel tests of rubber on copper samples. The results show that the energy dissipated in the forming, elongation and rupture of similar to 50 mu m long fibrils constitutes the major part of the work of separation. The experiments are characterized and modeled using a cohesive zone-enriched finite-element model. (C) 2010 Acta Materialia Inc. Published by Elsevier Ltd. All rights reserved.
