Brittle fracture is a failure mode by crack propagation rather than plastic deformation. It is caused by a material structure which becomes brittle at low temperatures. When would you most expect it
After wall-thinning at stress points
After long-term exposure to high temp.
After exposure to dynamic ‘shock load’
How does the repair code ASME PCC-2 differentiate between temporary and permanent repairs of pressure equipment?
