This video deals with
1. Stress ahead of a crack tip
2. Brief introduction to Irwin's model and Dugdale model
3. Crack opening displacement and crack tip opening displacement
4. Linear elastic plastic mechanics vs Elastic plastic fracture mechanics
5. Brief introduction to J-Integral (nonlinear strain energy release rate)
6. Fracture terminologies: Ductile vs Brittle, Shear Vs Cleavage, Granular Vs Fibrous, Intergranular vs Transgranular/intragranular
7. Design strategies to resist fracture: Compressive stresses on surfaces, Toughening of glass, Carburization of steel, Addition of Mn in high sulfur steels, Microstructure refinement
8. Tortuosity
Thanks for the video!
Thanks a lot
Sir do you have any recorded lectures on FATIGUE OF METALS..?
I have lectures on Fatigue of materials but need some editing. I shall put them on the channel in this month.
