Rational design of artificial micro-structured metamaterials with advanced mechanical and
physical properties that are not accessible in nature materials is challenging and important …

Abstract Mechanical Metamaterials (MMs) are artificially designed structures with
extraordinary properties that are dependent on micro architectures and spatial tessellations …

Data-driven models are rising as an auspicious method for the geometrical design of
materials and structural systems. Nevertheless, existing data-driven models customarily …

In this paper, an effective and efficient topology optimization method, termed as Isogeometric
Topology Optimization (ITO), is proposed for systematic design of both 2D and 3D auxetic …

Metamaterials are manufactured structures having extreme properties which do not exist in
nature. Topology optimization (TO) provides an excellent alternative to the intuition-based …

This paper develops an efficient multiscale topology optimization method for minimizing the
frequency response of cellular composites over a given frequency interval, which consist of …

Gradually stiffer (GS) mechanical metamaterial is a novel kind of adaptive structures under
nonlinear varying loads for cushioning and vibration damping in engineering. These man …

Structural metamaterials presenting negative values of one or more mechanical and
thermomechanical indices–namely the Poisson's ratio, the linear compressibility, and the …

Metamaterials with twist effects can exhibit remarkable rotational deformation under tension
or compression, a behavior that is uncommonly observed in conventional materials. Despite …

Literature on the mechanical performance of additively manufactured (AM) negative
Poisson's ratio (-υ) structures has been primarily focused on beam-based re-entrant …
