TL;DR: In this article , an averaged description of wrinkles through tension field theory was proposed to account for the presence of wrinkles in thin dielectric elastomers with compliant electrodes, which is consistent with available experimental data, in the sense that wrinkles can be maintained and restrained until when electromechanical instability takes place in the wrinkled membrane.

Journal ArticleDOI
TL;DR: In this article , a new form of maximum tangential strain criterion called 3D-MTSN is developed for predicting mixed-mode I/III fracture phenomenon, which is used originally for analyzing the mixedmode I and II fracture but extended its ability for mixed mode I/II fracture, and the influence of T-stress in addition to modes I and III stress intensity factors was also considered in driving the fracture toughness and fracture angle formulations of the 3D MTSN.
