If you are working on FEM for hyperelastic materials, then you might be interested in our new paper.
Self-excited vibrations represent a big concern in engineering, particularly in automotive, railway and aeronautic industry. Many lumped models have been proposed over the years to analyze the stability of such systems. Among the instability mechanisms a falling characteristic of the friction law and mode coupling have been shown to give friction-excited oscillations. The mass-on-moving-belt system has been studied extensively in Literature, very often adopting a prescribed form of the friction law and linearizing the contact stiffness.
Monolithic Bulk Metallic Glasses (BMGs) exhibit strain softening or elastic-perfectly plastic response under uniaxial loading. However, shape memory alloy particle reinforced BMG matrix composites show strong work hardening in experiments. In our recent paper published in Scripta Materialia, we explain the Mechanistic origins of work hardening in shape memory alloy particle reinforced ex-situ bulk metallic glass matrix composites through three dimensional finite element simulations.
Dear iMechanica,
We are very excited to share the news that our recent work on bioinspired materials with self‐adaptable mechanical properties is published in Advanced Materials.

We have published two papers on Ecoflex, a popular silicone polymer in recent days. The polymer is largely temperature- and strain rate-insensitive. It comes up with several Shore Hardnesses. We characterize five Shores and develop a novel Shore-dependent modelling framework

Dear members of iMechanica,
We are very pleased to announce the born of the first overlay journal in Solid Mechanics the so-called
Journal of Theoretical, Computational and Applied Mechanics https://jtcam.episciences.org
which is a scholarly journal, provided on a Fair Open Access basis, without cost to both readers and authors. The Journal aims to select publications of the highest scientific caliber in the form of either original research or review in Solid Mechanics.
