Engineering the Mechanics of Metamaterials

The Frazier Research Group explores the mechanics and dynamics of synthetic materials, with an emphasis on architected materials, multi-stability, wave propagation, and exceptional mechanical performance.

Designing materials with extraordinary behavior.

Our work combines theoretical, numerical, and experimental approaches to connect microstructural design with macroscale dynamic performance.

01 — CURRENT

Transition Wave Management

Investigating phase transformations and transition waves in multi-stable mechanical metamaterials to enable complex transformation behavior and controllable wave propagation.

02 — CURRENT

Mechanical Energy Absorption

Developing cellular metamaterials capable of predictable and reusable energy absorption under different loading directions and mechanical modalities.

03 — PREVIOUS

Nonlinear Supratransmission

Studying nonlinear wave transmission, multi-stability, and non-reciprocal behavior in phononic and mechanical metamaterial architectures.

From microstructure to macroscopic performance.

The group studies how carefully designed internal structures can produce novel optical, acoustic, and mechanical responses. Additive manufacturing and architected materials provide a platform for creating structures with properties not commonly found in conventional materials.

Multi-stable Metamaterials

Prescribed multi-stability can be used to elicit unique properties and exceptional performance from synthetic architected materials.
