Digital strategies for structured and architected materials design

Architected squirt-flow materials for energy dissipation

In the present study we explore material architectures that lead to enhanced dissipation properties by taking advantage of squirt-flow a local flow mechanism triggered by heterogeneities at the pore level. While squirt-flow is a known dominant source of dissipation and seismic attenuation in fluid saturated geological materials, we study its untapped potential to be incorporated in highly defor...

Fabrication of 3d Micro-architected/ Nano-architected Materials

Multistable Shape-Reconfigurable Architected Materials.

Multistable shape-reconfigurable architected materials encompassing living hinges and enabling combinations of high strength, high volumetric change, and complex shape-morphing patterns are introduced. Analytical and numerical investigations, validated by experiments, are performed to characterize the mechanical behavior of the proposed materials. The proposed architected materials can be const...

Structured Design Strategies

Semiconductor designers are now in the business of system design and significant productivity improvements can only be reached through an additional investment upstream in architectural understanding. Chip layout strategies shall now result from such upstream decisions implying new developments in precharacterized cells used at the breadboard level, functional simulation using custom CAD tools....

Protocols for the Optimal Design of Multi-Functional Cellular Structures: From Hypersonics to Micro-Architected Materials

Cellular materials with periodic architectures have been extensively investigated over the past decade for their potential to provide multifunctional solutions for a variety of applications, including lightweight thermo-structural panels, blast resistant structures, and high-authority morphing components. Stiffer and stronger than stochastic foams, periodic cellular materials lend themselves we...
