... of these remarkable characteristics, HMSMs are promising candidates for the remotely controlled actuators. The magnetic actuation behavior of the hard-magnetic soft actuators (HMSAs) is considerably affected by the viscoelastic material behavior of HMSMs. In this article, we aim at developing an analytical dynamic...

...Markus J. Buehler Dynamic fracture is an important area of materials analysis, assessing the atomic-level mechanisms by which materials fail over time. Here, we focus on brittle materials failure and show that an atomistically derived progressive transformer diffusion machine learning model can...

The nonlinear dynamics is computed by using the method of multiple scales, which is validated by the harmonic balance method combined with the asymptotic numerical method. Then, the rules for controlling the two different...

... difference from the previous works is that we discover the significance of the stretch-dependent permittivity on the dynamic response, which has never been reported earlier. We find that the stretch-dependent permittivity can either increase or dramatically decrease the oscillation amplitude at certain...

...Rumeng Liu; Jiaye He; Jicheng Zhang; Lifeng Wang Fully atomistic simulations and a sandwich plate model are used to study the dynamic behavior of twisted 3R-MoS 2 bilayers. The simulations demonstrate that for a very small twist angle, the Moiré pattern leads to the symmetry breaking...
