About Me
Graduate of a Master of Sciences, I’m an engineer specialised in Structural Mechanics such as the ones found in aeronautics.

I've gained a overall understanding of the industry and applied research. I studied material shaping processes and stepped in mechanical design. I also developed transverse skills when I sold electrohydraulic systems for British and Irish customers during my previous position.
  • Conducted mechanical fatigue analyses on the A380 nose, centre fuselage and wing box sections (fail-safe, safe-life and widespread fatigue damage).
  • Computed equivalent mechanical stresses for different flight missions.
  • Modelled crack initiation and propagation on mechanical joints.
  • Analysed experimental results based on full-scale fatigue test.
  • Updated maintenance tasks in respect to airline feedbacks.

  • Developed B2B sales in mobile hydraulics in the UK and Eire.
  • Retailed components (motors, valves, fittings, workshop equipment, etc.) and looked for spare part replacements.
  • Designed electrohydraulic systems along with design department (power packs, control boxes, proportional spool valves, hydrostatic transmissions, multiple gear pumps, auxiliary lines, power take-offs, etc.)
  • Determined component requirements (mechanical driven-power, flow rate, pressure losses, hydraulic accumulator relaxations, cylinder buckling).
  • Took part in agricultural shows (SIMA, LAMMA and Midlands Machinery).
  • Followed up repairs (piston pumps), order shipments and provided after-sale services.

  • 3-month training at the headquarters prior to expatriation to the subsidiary based in the UK.

  • Wrote technical instructions for customer deliveries and manufacturing of agricultural machinery and subsequent upgrades.
  • Projected CAD views of complete machinery and exploded views of sub-assemblies on CREO Parametric.
  • Annotated assembly steps (bolt tightening, slinging, greasing, etc.) on Illustrator.
  • Updated BOMs on Windchill PDMLink (spare parts catalogue).
Learn more
  • Identified chemical, thermal and rheological constitutive models with global non-linear optimisation on Scilab.
  • Simulated preheating and filling of highly-reinforced thermosetting materials with mid-long discontinuous fibres (reshaping of epoxide resin / carbon fibre prepreg remnants with metallic inserts) on Moldflow Insight.
  • Simulated moulding process (curing, injection, cooling and mechanical behaviour).
  • Conducted statistical analysis and extrapolated manufacturing parameters.
  • Highlighted process enhancements on aeronautical parts (secondary structures).
Learn more
  • Studied constitutive models of titanium alloys for hot forming applications (process temperature from 600 to 800°C) in partnership with AIRBUS.
  • Optimised elasto-viscoplastic parameter with thermal depedency on Scilab.
  • Modelled surface contacts and structural non-linearities.
  • Analysed residual stresses, thickness variations and elastic springbacks.
  • Simulated forming of industrial parts on Abaqus/Explicit.
Learn more
  • Motorised horizontal movement of integrated deck oven lifter on PRO/Engineer Wildfire.
  • Supervised fabrication and experimentation of a prototype.
Learn more
  • Supervised maintenance traceability of the bogie drive axles.
  • Replaced defective parts (needle bearings, seals, bolts, etc.)
  • Performed ultrasound non-destructive experiments on sumps.

German Intensive Training

GRETA Nord Alsace, Saverne (France)

August 2013 to December 2013
This 240-hour German training gave me the aptitude to hold basic conversations in German.

Engineer in Structural Mechanics

ISAE-ENSMA (Postgraduate school in Mechanics and Aeronautics), Poitiers (France)

September 2008 to September 2011
ISAE-ENSMA is an engineering school focused on mechanics and aerotechnics (fluid mechanics, heat transfers, energetics and propulsion), as well as embedded systems in the field of transportation and more specifically aeronautics. The school provides a degree equivalent to a Master of Sciences.

I specialised in structural mechanics during the third year:
✔ Experimental stress analysis, compound durability, damage, fatigue, finite strains, aeronautical structures.
✔ Finite element modelisation, plasticity and viscoplasticity, material mechanical properties, rupture, compound materials.
