STRESS ANALYSIS
Design, Assessment and Structural Integrity
Working across a wide range of industries including Oil and Gas, Defence, Aerospace, Automotive and Medical, TECHDYN engineers are experienced at understanding and developing best solution for customer design. Applying the latest simulation techniques and design tools, supported by solid engineering principles, TECHDYN services team can support specific customer requirements or provide a complete turnkey engineering solution.
TECHDYN has long time experience in structural integrity assessment and design. We design and progress asset integrity management strategies that enable customers to avoid engineering failure, ensure regulatory compliance and optimise operating expenditure.
Current areas of activity
Areas in which we are particularly focused on improving the services and opportunities we provide to our customers include the following:
- flaw acceptance criteria and service life prediction
- compliance assessment with standard and design codes prescriptions:
- ASME Boiler and Pressure Vessel Code
- R5 and R56
- API 579
- DNV F101
- DNV F101
- BS7910
- Engineering Critical Assessment (ECA)
- impact and short transients
- metal forming
Benefits
The integrity of pipelines, plant, equipment and structures is vital to ensure a continued, safe and economic operation. Flaws such as cracks, welding defects and corrosion damage can occur during manufacture or service life. For safety critical items like pipelines and pressure vessels, platforms, mooring chains and risers, rigs and wind turbines the failure of a single component due to the presence of a flaw can threaten human life, as well as presenting severe economic and environmental consequences. Other flaws may be harmless, as they will not lead to failure during the lifetime of the component. Replacement or repair of such 'insignificant' flaws is unnecessary and economically wasteful. ECA enables us to make this assessment of whether a known flaw is 'critical'.
At TECHDYN we use state-of-the-art numerical tools to ensure the highest quality results. These include impicit and explicit finite element codes (MSC MARC, LS-DYNA, ABAQUS, etc..) integrated by customized user subroutines when needed.
