Find out about some of the R&D projects in which Zentech has participated and some of the areas of expertise available via our links with Brunel University London.
A Technology Strategy Board UK Government-funded development called DISPLACE was aimed at 'technology to increase the life & reliability of advanced lightweight Ni-based gas turbine discs'. Led by Rolls-Royce plc, participants included industry and academia:
- Rolls-Royce plc (Derby)
- Zentech International Limited
- Birmingham University
- Portsmouth University
A SBIR funded project with the Air Force Research Laboratory at Wright Patterson Air Force Base, Dayton, Ohio, USA was aimed at enhancing existing crack simulation capabilites in Zencrack.
Sample projects conducted by our associate consultants at Brunel University London
Through our close collaboration with many academics at Brunel University London, we have developed a wealth of expertise and capabilities in advanced numerical modelling.
Development of shell and solid-shell finite elements
Highly non-linear contact and self-contact analysis
Thermo-mechanical analysis for steel structures under fire
Meshless methods for fluid flow
Helicopter crashworthiness on water
Fluid-structure interaction is extremely challenging to simulate due to non-linearities (geometric, material and contact) and prediction of structural collapse for thin-walled structures with plasticity, damage and failure. In addition, the water model has to allow for cavitation and formation of shockwaves.
Fixed wing aircraft ditching
The main challenge for contact algorithms in this type of simulation is ingress of water after the structural failure. These challenges have been successfully addressed in modelling of helicopter and fixed wing aircraft ditching using transient non-linear finite element method coupled with smoothed particle hydrodynamics (SPH).
The same approach was used was used in the modelling of bird strike on fan blades and fuel sloshing.
