62. Fracture Modes and Stress Concentration

Basics of Mechanical Behavior of Materials
This video deals with
1. Different Fracture Modes: Mode I, Mode II and Mode III
2. Opening mode, Shearing mode, Tearing mode
3. Plane stress and Plane Strain condition of Fracture
4. Fracture Toughness variation due to specimen thickness
5. Notch Effect or Crack effect
6. Stress Concentration and Stress Concentration Factor
7. Notch Effect: Triaxial stress state
8. Plastic Constraint Factor: Ratio of Notched flow stress to unnotched flow stress

Can you please make a video on what happens at atomic level during tensile testing of ductile and brittle materials (explaining all phenomena like elastic deformation, upper and lower yield point, slip deformation, necking, cup and cone fracture, etc)?
