Finding the optimal solution in the design space
Our work using finite element analysis (FEA) technique provides safety and reliability assurance and reduces manufacturing and operating costs for companies across a broad range of industries.
Finite element analysis provides cost savings and reliability assurance via:
- simulation of the behaviour of structures and components under static, dynamic and cyclic loads
- simulation of materials under extreme loading such as high velocity impact, low or high temperature, high pressure, large strain
- ballistic resistance assessment, armor/anti-armor design
- weld modelling to predict residual stress and distortion
- stress or strain-based engineering critical assessments (ECAs) of flawed components
We use FEA and related numerical techniques for a broad range of applications. These include:
- support for fitness for service (FFS) assessments, engineering critical assessments (ECAs), and design verifications, when FEA and fracture mechanics expertise is required by the relevant standards, such as BS 7910, API 579, R6 and BS 7608
- simulation of structures at high rates
- development and implementation of proprietary damage models for limit strain capacity assessment
- design optimisation
- inverse analysis to carry out measurements based on FEA simulations.
- TECHDYN uses state-of-the art commercial software to perform FEA, as well as developing in-house software tools to supplement the commercial codes. TECHDYN is technology partner of MSC SOFTWARE.
Industry sectors that benefit from our FEA services include:
- oil and gas
- power generation
- structural geology
Simulation of material resistance under impact or blast load helps in estimating vulnerability of structures reducing costs for experiments. ECAs can increase the allowable time between inspections, and therefore reduce operating costs. ECAs are also used to support decisions about life extension, repair and replacement in pipeline design. Similalry, simulation of biological organs can help in understanding the development of traumatic injuries while simulation of deformation processes at earcth crust scale can clarify the process of faults formation and provide indication about earthquake precursors.
Effective design of components allows our clients to achieve a satisfactory balance between factors such as performance within specifications, weight, cost, complexity and sustainability. Finding the correct balance improves profitability and can also provide new unique selling points. The interdisciplinary approach taken by TECHDYN is of great value during these activities. Strong links between laboratory and modelling simulation allow the collation and use of high-quality input data for models, and their validation through physical testing.
