1 Answer

Answer :

Seven factors influencing type of failure are :
Type of material (inherent structure properties),
Manner of loading (Static versus dynamic),
Range of imposed stress,
Strain rate (static, dynamic, impact),
Stress distribution (discontinuity in material/shape),
temperature, and
surface treatment.
