3 0 0 3
UNIT I ELEMENTS OF SOLID MECHANICS 9
The geometry of stress and strain, elastic deformation, plastic and elasto-plastic
deformation - limit analysis – Airy’s function – field equation for stress intensity factor.
UNIT II STATIONARY CRACK UNDER STATIC LOADING 9
Two dimensional elastic fields – Analytical solutions yielding near a crack front –
Irwin’s approximation - plastic zone size – Dugdaale model – determination of
integral and its relation to crack opening displacement.
UNIT III ENERGY BALANCE AND CRACK GROWTH 9
Griffith analysis – stable and unstable crack growth –Dynamic energy balance –
crack arrest mechanism –K1c test methods - R curves - determination of collapse
load.
UNIT IV FATIGUE CRACK GROWTH CURVE 9
Empirical relation describing crack growth law – life calculations for a given load
amplitude – effects of changing the load spectrum -- rain flow method– external
factors affecting the K1c values.- leak before break analysis.
UNIT V APPLICATIONS OF FRACTURE MECHANICS 9
Crack Initiation under large scale yielding – thickness as a design parameter – mixed
mode fractures - crack instability in thermal and residual stress fields - numerical
methods
TOTAL :45 PERIODS
