Forensic materials engineering methods including macroscopic inspection, microscopic examination, chemical analysis and mechanical testing. Specifically this will cover:Mechanical testing: stress-strain, creep, fatigue, impact, hardness, fracture toughness, abrasion, friction, tear, compression.Thermal testing: Tg, Tm, flame testing, thermal analysis.Optical and Electron Microscopy: lighting variations, scanning/transmission electron microscopy, preparation of specimens.Detection and Identification: EDXA, chromatography, X-ray diffraction, atomic absorption, mass and emission spectrography.Optical testing: colour, haze, gloss, birefringence.Non-Destructive Testing: X-radiography, []-radiography, ultrasonic testing, dye-penetrant, magnetic particle inspection.Processability testing: viscosity, cure shrinkage, orientation.Test procedures: standards, need for testingEnvironmental testing: chemical resistance, stress cracking, ageing, accelerated corrosion.Fire performance testing: ignitability, spread of flame, smoke, toxic gases, LOI.Solderability testing: solder balance, microscopic evaluation.In addition to the above, the failure of products and processes will be considered together with case studies of major disasters where materials failures were considered significant contributors.
