The bending of beam creates tendency of particles to side pass over each other within the beam is termed as shear.
The section may be subjected to shear due to bending due to torsion, due to punching.
- Bending – Flexural Shear
- Torsion – Torsional Shear
- Punching – Punching Shear
Shear stress Variation Over Rectangular Section of Linearly Elastic Homogeneous Material
The picture at last is not in scale, so the numbering suggests 1 and 3 are flexural shear cracking and up to 2 is flexural crack.
