Question
Read 2-34 through 2-39 of the Steel Construction Manual and answer the following: Name four conditions that tend to cause brittle fracture
Zones of reduced notch toughness
High Charpy V-notch toughness
Cuts with re-entrant corners that include a large radius between cut lines
low-temperature service
Reduced section due to corrosion
Uni-axial plane strain beyond yield strength
Residual stresses from welding
Triaxial stress state
High strain rate loading
a.Zones of reduced notch toughness

Explanation / Answer
The four condition that tend to cause brittle fracture of steel are:
1. Low- temperature service
2. High strain rate of loading
3. High charpy V notch toughness
4. Residual stress from welding.
