MF3005 Engineering Failure Analysis Syllabus:
MF3005 Engineering Failure Analysis Syllabus – Anna University Regulation 2021
COURSE OBJECTIVES:
The main learning objective of this course is to prepare students for:
• Explain the importance of failure study of mechanical components.
• Discuss about various material characterization tools and analyse the failure.
• Equip students with knowledge on how to design against failures and Skills required in carrying out failure analysis
• Understanding of failure against wear and creep loading
• Understanding of failure in joints and degradation
UNIT I INTRODUCTION
Material failure modes and their identification- Tools for failure analysis: Optical microscopy, Transmission electron microscopy, Scanning electron microscopy. Systematic approach to failure analysis.
UNIT II MECHANICAL ASPECTS OF FAILURE
Tensile test – Static loading – Combined stress -Principal stresses – Theories of failure -Triaxial stresses and constraint – Plane stress – Plane strain – Stress concentration factors and notch sensitivity – Shock and impact loading.
UNIT III FATIGUE
Loading under high cycle fatigue conditions-Test methods- S-N-P curves- endurance diagrams influence factors – Low cycle fatigue, fretting fatigue; Fatigue design for combined stress; cumulative damage and life prediction, statistical interpretation of fatigue test data. Failures related to corrosion -hot corrosion and stress corrosion cracking-Damages due to hydrogen- Creep of metallic materials-service failures during high temperature serviceFailures related to wear
UNIT IV FRACTURE MECHANICS AND FAILURES
Fracture processes -Meaning of ductile and brittle fracture – Effect of strain rate and temperature Linear elastic fracture mechanics – fracture mechanics principles in design practice – Elastic Plastic fracture mechanics – Examples of crack-growth Analysis for cyclic loading.
UNIT V FAILURES IN JOINTS AND FASTENERS
Welded constructions and screw fastenings – Environmental degradation – Embrittlement of metals and alloys.
TOTAL : 45 PERIODS
