Dynamic interaction
Models that treat the structure, foundation, piles and soil as one coupled vibrating system.

We study what happens at the interface.
Structures do not stop at the foundation. We model how structures, foundations, soil and water move together, then use that understanding to design safer, quieter and more efficient systems.

News & highlights
A better shape is only half the design.
We optimize a printed part’s shape and material direction together, while checking that it can carry the load. Discover the work led by Bruno Denadai.

Coupled problems need coupled thinking.
Our work connects structural dynamics, geomechanics, wave physics, optimization, bio-inspired mechanics and computational methods. The common thread is interaction between parts, materials, living systems, physical domains and scales.

Vibration control
Barriers, periodic systems and metamaterial concepts that redirect or attenuate vibration.
Ground waves · barriers · periodicity · vibration attenuation03
Optimization
Computational design methods that account for flexible supports, interfaces and failure modes.
Topology optimization · stress · buckling · flexible supports04
Offshore multiphysics
Coupled models of water, seabed and structures for vibration and marine-protection questions.
Scholte waves · PML · submerged barriers · fluid-soil coupling05
Bio-inspired engineering
We study how roots and soil organisms interact with the ground, then translate those mechanics into new structural and robotic concepts.

Connections
A wider research community.
Long-term collaborators, funded international partners and interdisciplinary project teams extend the methods and questions the lab can address.
Collaboration network
From Unicamp to Delft, Melbourne, Amsterdam, Brown and Simon Fraser.
Each relationship is tied to a shared project, publication or intellectual history.

Models are only useful when they survive scrutiny.
We derive, implement and verify before using computation to make mechanical claims or design decisions.
