MD-Lab supported a clinical forensic engineering investigation into the mechanical failure of a proximal femoral nail assembly. The project focused on fractographic analysis of the recovered hip screw and sleeve, translating fracture-surface evidence into a clear explanation of how the implant failed.
A controlled experimental characterization project for ELVAL COLOUR S.A., focused on the damping behavior of composite aluminium plates. MD-Lab developed the mechanical test setup, manufactured a dedicated auxiliary aluminium plate and fixture system, and carried out vibration measurements according to DIN EN ISO 6721-1 and -3. Detailed numerical results and material comparisons are omitted from this public summary due to confidentiality.
The Gearless Differential project investigates a cam-track differential architecture that replaces conventional side and spider gears with identical wavy cam-track disks, guided rolling members and a geared retainer. The work formalizes the geometry required for rolling contact, verifies the kinematics through simulation, and evaluates a representative passenger-car configuration using contact stress and fatigue-life assessment.
MD-Lab research on concrete at cryogenic temperatures develops an experimental route for measuring the linear coefficient of thermal expansion of cylindrical concrete specimens down to approximately -160 °C. The work addresses the need for reliable thermal-strain data in refrigerated liquefied-gas containment structures, where concrete response is governed by coupled heat transfer, pore-water phase change and aggregate-paste mismatch.
For STASY S.A., MD-Lab developed a repeatable laboratory procedure for assessing the thermal behavior of old rail lubricating grease under controlled heating conditions. MD-Lab designed the thermal-test workflow, configured the heating and temperature-monitoring setup, recorded temperature history and timed observations, and prepared the technical documentation. Supporting chemical analysis was carried out separately by the Fuels and Lubricants Technology Laboratory of NTUA.
MD-Lab documented and interpreted the loading mechanisms of the French Wharf of Lavrion, an 1888 industrial-heritage structure built for the movement of minerals, coal and commercial goods. The project turns a corroded and partly incomplete machine system into a clear engineering narrative for restoration, public interpretation and accessible reuse.
