List At Least Two Factors That Promote The Transition From Ductile To Brittle Fracture? |
|
Answer» The manner of LOADING and the rate of loading promote the TRANSITION from ductile to brittle fracture. A machine member may have ductile failure under static loading but may fail in brittle FASHION when the load is fluctuating. Similarly a material may evidence ductile failure under tensile loading at ordinary testing speed, but if the load is APPLIED at a HIGH velocity then failure may be brittle.
