Highlights Mechanical design methods and theoretical models of soft hard mechanical metamaterials are reviewed based on deformation mechanisms. Multifunctional benefits limitations reviewed, comprehensive performances optimization categorized. Industrial applications perspectives challenges discussed.

An anisotropic continuum-molecular model based on pair potentials for describing the linear static and dynamic behavior of periodic heterogeneous Cauchy materials is derived in framework peridynamic theory. Non-central pairwise actions are assumed as work-conjugates to specific deformation variables. A constitutive law, depending trigonometrically material fiber direction preserving elastic sym...

Protection of critical infrastructure in an urban environment is a challenging task, specifically against the vehicle bourne improvised explosive device threat. To design to withstand this evolving threat, novel solutions and advanced materials need be developed. One such material interest are auxetics. This study experimentally analysed mitigation blast response auxetic re-entrant honeycomb st...
