Attained practical, hands-on experience conducting various fatigue and fracture tests for the aerospace and defense sector. • Mechanical tests performed included tensile, fracture toughness, drop-weight tear, load-controlled high cycle fatigue, strain-controlled low cycle fatigue and fatigue crack propagation. • Performed test-frame set-ups, verifications and calibrations of testing apparatus (temperature controllers, extensometers, LVDTs, servo-valve dynamic signal tuning and test frame alignment), test software programming, post-test analysis and results reporting. • Acquired a thorough familiarity with fatigue & fracture testing standards, specifications and accreditation requirements including ASTM standards, ISO 17025 and NADCAP AC7101.Notable Achievements:• Assisted in the development and implementation of testing procedures for critical crack size detection in unique geometric features using the Direct Current Potential Drop (DCPD) crack monitoring method. Performed best-fit analysis in establishing DCPD vs. crack-size relationships which were used to determine product fatigue life. Presented full testing procedure and analysis methodology to FAA to attain testing conformity.
