Our service covers non-linear static and dynamic analysis, including collision and other applications. These include specialist areas such as fracture and fatigue, design optimisation, fluid structure interaction and localised stress analysis to support safety assessments.
Linear static analysis is used to develop an understanding of a structure’s behaviour before more complex analyses and validation exercises are undertaken. It is often used in detailed stress analysis and, in some cases, can provide sufficient results without the need for more expensive procedures.
The increase in computing power and capacity and the enhanced capabilities of the latest Finite Element (FE) software enables increasingly sophisticated analyses to be performed such as ‘multi-physics’ analyses, optimisation and design studies, and a range of specific problem solutions e.g. fatigue and fracture assessments.
QinetiQ’s stakeholders and customers can benefit from the reassurance and added value provided by our specialist team and world class expertise in FE analysis.
The scope for dynamic analysis continues to grow and QinetiQ has a wealth of experience in a range of areas and has extensive experimental test data to support and inform our analyses for even the most complex application. The grounding of submarines is a good example. Here, the analysis will involve structural dynamics, contact, fluid-structure interaction, non-linear material behaviour and structural response under hydrostatic pressure.
Our marine structural analysis team have worked with global defence and commercial marine customers for more than 25 years.
These include UK Ministry of Defence, BAE Systems, Babcock, Rolls-Royce, Defence R&D Canada, Australian Submarine Corporation, Navantia, Lloyds Register, Shell and BP.
Support RN GRP Minehunters
QinetiQ Maritime Structural Analysis team provides specialist support for the Royal Navy’s minehunter fleet. Dealing with glass-reinforced plastic (GRP) hulls requires specialist structural knowledge. GRP materials behave in significantly different ways to conventional ship steels and can be susceptible to effects of environment (seawater immersion, temperature) and have particular, but well-understood, damage, fracture and failure mechanisms. QinetiQ support the Naval Authority to keep these ships operational.
