Two switchable, mesoscopically periodic materials were created by combining crystalline colloidal array (CCA) self-assembly with the temperature-induced volume phase transition of poly(N-isopropylacrylamide) (PNIPAM). Body-centered-cubic CCAs of hydrated, swollen PNIPAM particles Bragg-diffract infrared, visible, and ultraviolet light weakly, whereas arrays of compact shrunken particles diffrac...

This article presents a consistent computational framework for multiscale first-order finite strain homogenization and stability analyses of rate-independent solids with periodic microstructures. The formulation is built on priori discretized microstructure, algorithms computing the matrix representations homogenized stresses tangent moduli are consistently derived. results lose their validity ...

In this paper we describe a fast algorithm for generating periodic RVEs of polycrystalline materials. particular, use the damped Newton method from semi-discrete optimal transport theory to generate 3D Laguerre tessellations (or power diagrams) with cells given volumes. Complex, polydisperse up 100,000 grains prescribed volumes can be created in few minutes on standard laptop. The relies Hessia...

The distribution of emergency perishable materials is crucial for rescue operations in disaster-stricken areas. However, the freshness these changes over time, affecting quantity that can be distributed to demand points at different stages. To address this issue, paper proposes a novel approach. Firstly, piecewise function constructed describe impact on quality and time Secondly, establishes ve...
