Simulation
PRINCIPIA expertise in simulation is applied in several industrial sectors such as Marine, Offshore, Defence, Energy, Aerospace, Civil Engineering, Transportation …
This expertise supports the entire product lifecycle: pre-design, design, installation, maintenance and dismantling.
Structural analysis
- Linear and Non-linear behaviours :plasticity, buckling, contact
- Metallic, Plastic and Composite materials
- Multi-scale (micro/macro) and homogenization
- Fatigue life assessment of steel and elastomeric components
- Failure and Crack propagation
- Dynamic vibratory response
- Fast Dynamics
- Coupling with fluid and thermal effects
Use of best in class products such as ABAQUS™, ANSYS™, LS-DYNA™, PERMAS™, DeepLines™ and NSO/FASTRUDL™
Project examples:
- Accidental events : seism, shock, blast, collision
- Code check : AISC, API, ASME, CODETI, Eurocode, RCC-M, RCC-MR, …
- Classification Society’s Rules : ABS, BV, DNV, Lloyd’s,…
Fluid dynamics
- Multi-phase flows
- VOF free surface model
- Incompressible and compressible flows (high and low mach)
- Cavitation model
- Fluid/Solid thermal coupling
- Heat transfer condensation model
- Rigid structure/fluid coupling
Project examples:
naval hydrodynamics, sloshing, wave impacts, breaking waves, wave resistance, sea keeping, trajectography of solid structures under the action of flow
Fluid-structure interaction
- Shocks involving structures and inner/outer fluids
- Dynamic response of structures in presence of liquid
Project examples:
slamming impacts of ships, sloshing impacts in tanks, response to shock waves in fluids
