Mechanical properties are physical properties that a material exhibits upon the application of forces. Examples of mechanical properties are the modulus of elasticity, tensile strength, elongation, hardness and fatigue limit.
The shape and trajectory of a crack plays a crucial role in material fracture. High-precision experiments now directly capture this phenomenon, unveiling the intricate 3D nature of cracks.
Topological solitons can be realised in a range of platforms that have the potential for processing topologically protected information. Here, the authors identify a class of vector solitons in a mechanical lattice, showing superposed kinks and invertible polarizations, with implications for nonlinear topological mechanics.
Utilizing an epoxy-amine chemistry, the authors demonstrate a thermoset epoxy that is reprocessable and tough, achieving improved sustainability for this widely used plastic material.
Additive manufacturing is known to create microstructures that cannot be achieved by conventional alloy processing. Here, heat treatment of an additively-manufactured aluminum alloy creates a hierarchical microstructure with a large number of precipitates, achieving high strength and ductility.
The shape and trajectory of a crack plays a crucial role in material fracture. High-precision experiments now directly capture this phenomenon, unveiling the intricate 3D nature of cracks.
When cracks creep forward in our three-dimensional world, they do so because of accompanying cracks racing perpendicular to the main direction of motion with almost sonic speed. Clever experiments have now directly demonstrated this phenomenon.
Optimisation tasks in the inverse design of metamaterials with machine learning were limited due to the representations of generative models. Here the author comments a recent publication in Nature Communications which generates a latent space representation that unlocks non-linear optimisations.
