Fracture Mechanics and Failure Analysis for B.Tech 8th sem is covered here. This gives the details about credits, number of hours and other details along with reference books for the course.
The detailed syllabus for Fracture Mechanics and Failure Analysis B.Tech (R13) eighthsem is as follows
OBJECTIVES:
- To introduce the basic concept of fracture mechanics and failure analysis
- Import knowledge on mechanics of fracture during static and dynamic loading
- Understanding the failure mechanism of creep rupture.
- Understand the mechanism of wear and corrosion and knowledge on prevention
UNIT I : BASIC CONCEPTS IN FRACTURE MECHANICS [9 Hours]
The geometry of stress and strain, elastic deformation, plastic and elasto-plastic deformation, Brittle fracture: Griffiths theory, Ductile fracture, Probabilistic aspects of fracture mechanics – Microstructure
UNIT II : MECHANICS OF FRACTURE- STATIC LOADING [9 Hours]
Elastic fields – Analytical solutions yielding near a crack front – Irwin’s approximation – plastic zone size – Dugdaale model – J integral and its relation to crack opening displacement. Strain energy release and stress intensity factor. Evaluation of fracture Toughness of different materials: size effect & control.
UNIT III : FAILURE ANALYSIS OF FATIGUE FRACTURE [9 Hours]
Fundamental sources of failures- Deficiency in design, Empirical Relation describing crack growth by fatigue – Life calculations for a given load amplitude – effects of changing the load spectrum – Effects of Environment. Micro structural analysis of fatigue failures, some case studies in analysis of fatigue failures.
TOTAL: 45 PERIODS
OUTCOMES:
- Ability to design structure to prevent failure from the internal defect that unit within the structure
- Ability to design structure to prevent fatigue and creep
- Ability to define different deformation and related theories
- Ability to analyse the corrosion and wear failure and system methods to prevent corrosion and wear.
