COMPRESSION &
SHEAR
- Normal Stress & Strain
- Shear Stress & strain
, Example 1: A punch for making holes in steel plates is shown in
Fig (a). Assume that a punch having diameter d = 20 mm is used
to punch a hole in an 8-mm plate, as shown in the cross-sectional
view Fig (b). If a force P 110 kN is required to create the hole,
what is the average shear stress in the plate and the average
compressive stress in the punch?
