Advanced FEA for Aerospace & Hi-tech
When standard linear analysis isn't sufficient, our team delivers specialist finite element solutions, from localised plasticity and ultimate failure assessment to structural optimisation and crashworthiness. We work across offshore energy, aerospace, and hi-tech industries.
Our engineers combine deep theoretical knowledge with industry-leading software to solve problems that demand more than code-check calculations.
Specialist Capabilities
Localised Plasticity Analysis
When stresses exceed allowable limits, we perform detailed elasto-plastic FEA to assess local yielding, stress redistribution, and whether the structure can safely tolerate the overload without compromising integrity.
Ultimate Failure Analysis
Assessment of extensive plasticity under global collapse scenarios. We determine the true load-carrying capacity of structures beyond elastic limits, critical for accidental load cases and structural reassessment.
Structural Optimisation
We optimise structural designs to meet specific mass, stress, or frequency criteria, reducing weight while maintaining performance and compliance with design codes.
Crashworthiness Analysis
Collision and energy absorption assessment for aerospace and hi-tech applications. Crashworthiness analysis is the counterpart of ship collision in the offshore world, evaluating how structures deform and absorb energy during impact events.
Time and Frequency Domain Strength & Fatigue
Time and frequency domain strength and fatigue analysis where history from signals or loading statistics are known. We assess structural life under realistic operational loading conditions.
Bolted Connection Analysis
From simplified bolt representations for global models to fully modelled bolted connections for critical applications, including preload, contact, and fatigue assessment of the joint.
Weld Analysis
Detailed assessment of welded joints including hot-spot stress extraction, structural stress methods, and fatigue life prediction in accordance with applicable design codes.
Process Automation
We automate repetitive FEA workflows using Python, from model generation and load application to post-processing and reporting. This reduces computational time and eliminates manual errors in large parametric studies.
Software
We run both major FEA platforms, giving us the flexibility to match the right solver to the problem:
- ANSYS Mechanical: implicit nonlinear, buckling, optimisation
- Ansys Discovery / SpaceClaim: geometry preparation and rapid simulation
- Simcenter (Siemens): advanced multiphysics and structural simulation
- NASTRAN: industry-standard linear and nonlinear solver
- Python & Matlab: workflow automation, pre/post-processing, parametric studies
Standards & Codes
Our analyses are performed and validated against internationally recognised standards:
- DNV-RP-C208: Determination of structural capacity by non-linear FE analysis
- DNV-RP-C203: Fatigue design of offshore steel structures
- NORSOK N-004: Design of steel structures
