Highly-stretchable 3D-architected Mechanical Metamaterials

Key contribution to the field: Most of exisiting additive manufacturing techologies are focused on rigid materials from rigid plastics to metals, but manufacturing sructures with both highly complex architectures and high stretchability is challenging. Here, we introduce a new stereolithography-based additive manufacturing technology to fabricate elastomer lattices with complex 3D architectures and high strechability.

Lightweight Mechanical Metamaterials with Tunable Negative Thermal Expansion

Key contribution to the field: Manufacturing of composite structures with tailored 3D microstructures is challenging with existing manufacturing technologies; here we introduce a new stereolithography-based additive manufacturing technology to fabricate multimaterial littice structures with nearly arbitrary 3D microarchitectures.

Dynamic creation and evolution of gradient-nano-grained structures in single-crystal metallic microcubes

In an article published today in Science, we have demonstrated the creation of an extreme gradient-nano-grained (GNG) structure in single-crystal microcubes through high-velocity impact. We use the defect-free single-crystal silver microcubes, synthesized using a seed-growth process, as the model system, and fire them at supersonic velocities onto a rigid target to create the GNG structure.

Deterioration of the quality of the Elsevier journal printing

Many Mechanics journals are printed by Elsevier. Unfortunately, I observe huge deterioration of the quality of the printing.

Quasi-periodicity and multi-scale resonators for the reduction of seismic vibrations in fluid-solid systems

This paper presents a mathematical model for an industry-inspired problem of vibration isolation applied to elastic fluid-filled containers. A fundamental problem of suppression of vibrations within a finite-width frequency interval for a multi-scale fluid-solid system has been solved. We have developed a systematic approach employing full fluid-solid interaction and dispersion analysis, which can be applied to finite and periodic multi-scale systems.

Flaw sensitivity of highly stretchable materials

Elastomers and gels can often deform multiple times their original length. The stretchability is insensitive to small cuts in the samples, but reduces markedly when the cuts are large. This work shows that this transition occurs when the depth of cut exceeds a material-specific length, defined by the ratio of the fracture energy measured in the large-cut limit and the work to rupture measured in the small-cut limit.  This conclusion generalizes a result in the fracture mechanics of hard materials.
