PLASTIC DEFORMATION IN BRITTLE AND DUCTILE FRACTURE

reportActive / Technical Report | Accession Number: AD0674852 | Open PDF

Abstract:

An effort is made to cover the full elastic-plastic range from fractures which initiate and propagate at nominal or net stress in the elastic range to the fractures at fully plastic or limit load conditions. Similarities and differences of behavior between steels which are highly rate-sensitive and aluminum alloys or other rather insensitive materials are examined. A demonstration is given of the likelihood of confusing limit load fractures with low stress fractures.
