Less Is More: Hollow-Truss Microlattice Metamaterials with Dual Sound Dissipation Mechanisms and Enhanced Broadband Sound Absorption.

Publication Type: Academic Journal

Source(s): Small (Weinheim an der Bergstrasse, Germany) [Small] 2022 Nov; Vol. 18 (44), pp. e2204145. Date of Electronic Publication: 2022 Sep 22.

Authors:

Abstract: Being a lightweight material with high design freedoms, there are increasing research interests in microlattice metamaterials as sound absorbers. However, thus far, microlattices are limited to one sound dissipation mechanism, and this inhibits their b...

ESCAPING UNKNOWN DISCONTINUOUS REGIONS IN BLACKBOX OPTIMIZATION.

Publication Type: Academic Journal

Source(s): SIAM Journal on Optimization. 2022, Vol. 32 Issue 3, p1843-1870. 28p.

Abstract: The design of key nonlinear systems often requires the use of expensive blackbox simulations presenting inherent discontinuities whose positions in the variable space cannot be analytically predicted. Without further precautions, the solution of relate...
