...Jun-Feng Zhou; Kai-Ming Hu; Hui-Yue Lin; Zhi-Qi Dong; Tian-Yu Zhao; Xiu-Xuan Li; Guang Meng; Wen-Ming Zhang The dynamic instability of stiff films on compliant substrates has received sustained attention due to the potential applications in flexible functional devices. Film/substrate system-based...

...Fatemeh Jafarabadi; Shuolun Wang; Maria A. Holland Over the past decades, the buckling instability of layered materials has been the subject of analytical, experimental, and numerical research. These systems have traditionally been considered with stress-free surfaces, and the influence of surface...

.... The critical torques for the first and the secondary instability of monofilaments under different axial forces are obtained. Three stability criteria of filaments subjected to torsion and tension, due to Timoshenko, to Ross, and to Dwivedi and co-workers, are accessed within the context of measurement data...

... and instability of soft hollow cylinder is analyzed. By incorporating surface energy density function into the constitutive model of a hyper-elastic theory, explicit solutions are obtained for the large deformation of soft hollow cylinder under the uniform pressure loading and geometric everting. The surface...

...Danming Zhong; Junjie Liu; Yuhai Xiang; Tenghao Yin; Wei Hong; Honghui Yu; Shaoxing Qu; Wei Yang A soft adhesive layer bonded between two rigid substrates, which are being pulled apart, may exhibit diverse instability phenomena before failure, such as cavitation, fingering, and fringe instability...

... Wrinkles in graphene with desirable morphology have practical significance for electronic applications. Here we carry out a systematic molecular dynamics study of the wrinkling instability of graphene on substrate-supported nanoparticles (NPs). At a large NP dispersion distance, a monolayer graphene...

...J. Wu; K. C. Hwang; J. Song; Y. Huang Based on the finite-deformation shell theory for carbon nanotubes established from the interatomic potential in Part I of this paper, we have studied the instability of carbon nanotubes subjected to different loadings (tension, compression, internal...

...Bo-Wun Huang; Jao-Hwa Kuang This study investigates dynamic instability in a high-speed drilling process. A pretwisted beam is used to simulate the drill. The time-dependent nature of the thrust force and the drilling depth is considered in the equation of motion of the drill. A moving Winkler-type...
