Summary: This study presents the first attempt to investigate the internal friction of complex ferroelastic twin patterns using atomistic molecular dynamics simulations. Linear and non-linear internal friction regimes are observed at different stress amplitudes, separated by a pinning/depinning threshold. The motion of twin boundaries generates non-linear anelasticity, where the stress-dependent internal friction increases to a maximum and then decays. The internal friction is directly related to the motion of needle twins.

Summary: This study demonstrates the nonmonotonic effect of Te vacancy defects on the friction of MoTe2. Increasing Te vacancy density leads to an overall increase in friction force, but the variation is nonmonotonic. The change in the maximum sliding energy barrier and uneven charge distribution are the main factors contributing to this effect.

Summary: By employing first-principles calculations, this study reveals that the friction force can be reduced and a negative differential friction coefficient can be realized upon increasing the normal load on one layer of ferroelectric In2Se3 over another commensurate layer of In2Se3, breaking the classic Da Vinci-Amontons law. This counterintuitive observation is attributed to the delicate interplay of interfacial van der Waals repulsive interactions and the electrostatic energy reduction due to enhanced Se-In ionic bonding under load, providing insights for the design of high-performance solid lubricants and mechanical-electronic nanodevices.

Summary: The efficacy of peening treatment can be improved by using high-amplitude short duration pulsed current, as demonstrated in the study of electropulsing-assisted ultrasonic nanocrystal surface modification (EP-UNSM). EP-UNSM process combines ultrasonic peening and electropulsing to enhance the plasticity of the target metal Ti64, resulting in deeper plastic deformation layer, higher surface hardness, and greater compressive residual stresses. The pulsed current effectively improves the peening efficacy, making EP-UNSM an effective method for strengthening Ti64.

The model is validated using experimental data. By establishing a database connecting LSP parameters with residual stress, the effects of LSP parameters on residual stress distribution can be studied and optimal LSP parameters for desired residual stress characteristics can be obtained. This multi-objective optimization method is expected to guide LSP experiments effectively.

Summary: This study demonstrates the improvement of mechanical properties and reduction of coefficient of thermal expansion (CTE) in graphene oxide (GO)/epoxy (EP) nanocomposites by enhancing the interface between GO and EP through functionalization and incorporating rigid-flexible interphases. The results reveal that the SiO2-PEA-GO hybrid exhibits better strengthening and toughening effects, as well as lower CTE, compared to the PEA-GO hybrid due to the presence of rigid-flexible interfaces with higher bonding strength and better energy dissipation mechanisms. Additionally, the nanocomposites with longer polyetheramine (PEA) molecules in the rigid-flexible interphases demonstrate higher strength and toughness, while maintaining a lower CTE. This work provides a promising strategy for constructing adjustable flexible-rigid interfacial structures and offers potential in developing GO/EP nanocomposites with high mechanical properties and low CTE.
