Metamaterials are those materials that are not found in nature and are artificially manufactured materials. The properties of such materials are derived from their internal microstructure (geometrical configuration) and not from their chemical composition. The concept of metamaterials was initially coined in the context of optics and electromagnetism. The properties of the metamaterials on the […]
Read MoreAuxetic metamaterials are a class of metamaterials that possess auxetic property. The term auxetic refers to the materials with a Negative Poisson’s ratio (NPR), contrary to the naturally occurring materials with a positive Poisson’s ratio. Generally, naturally available materials get compressed in the lateral direction when stretched in the longitudinal direction. Contrary to this, if […]
Read MoreLightweight sandwich structures are commonly used in aircraft that contain upper and lower skins made up of glass or carbon fabric composite with a honeycomb or foam core. Replacing them with mechanical metamaterials such as auxetic re-entrant honeycombs can show better performance. The mechanical metamaterials research field is still in its early stages and mostly […]

LAMMPS (Large-scale Atomic/Molecular Massively Parallel Simulator) is a classical molecular dynamics code.“LAMMPS has potentials for soft materials (biomolecules, polymers) and solid-state materials (metals, semiconductors) and coarse-grained or mesoscopic systems. It can be used to model atoms or, more generically, as a parallel particle simulator at the atomic, mesoscale, or continuum scale.” Pre Installation Steps:-These installation […]
