Material and joint response
Previous studies document static and fatigue characterisation of materials and joints. The specimen, loading conditions and required measurements define the feasibility of a new campaign.
Strain, vibration and temperature
These measurement categories feature in existing research. Sensors, acquisition settings, operating ranges and facility access must be confirmed for each investigation.
Model correlation and data processing
Experimental results can be compared with finite element and analytical models, using scientific programming to evaluate predictions and document the analysis.
04 / Research facilities
What we can investigate
Previous studies and datasets. New materials or loading cases need a specific feasibility check.
Fatigue and durability
Investigate behaviour under repeated loading, characterise fatigue response and compare life predictions with experimental results.
Mechanical characterisation
Study the mechanical response of engineering materials and components. Previous research includes polymer composites, hybrid joints and the influence of temperature on material behaviour.
Joints and structural integrity
Connect measurements and computational analysis to assess welded components and mechanical joints, including residual stresses and fatigue response.
Numerical–experimental validation
Combine finite element analysis with mechanical measurements to examine model predictions. Research experience includes strain, vibration and temperature measurements and component-level correlation.
Engineering data and methods
Process experimental data, develop scientific software and compare analytical or computational methods. Reproducible datasets and documented algorithms support interpretation and model validation.
