Title: Determining plane strain fracture toughness and the j-integral for solid materials using stress field modified miniature specimens
Inventor: MANAHAN MICHAEL P SR
IPC: G01N3/00
Filed: 1989-01-18
Granted: 1994-01-11
Abstract: ABSTRACT A method of determining the mechanical behavior of solid materials by using stress field modified miniature specimens.   The method is an improvement in the method of determining mechanical behavior information from specimens only so large as to have at least a volume or smallest dimension sufficient to satisfy continuum behavior in all directions. Mechanical behavior of the material is determined from the measurements taken during the loading of the specimen resulting in the formation of cracks and/or the  further propagation of cracks in the miniature specimen.  The specimens include means for applying  additional  stress  field modifying loads upon  the  specimens  during  the  test.    These additional loads result in a desired stress state in the specimen which could not be achieved otherwise. A  particular  example  is  the  introduction  of  a transverse  tensile  load  during  a  bend  test  to increase  the transverse  stress  field  to achieve plane strain conditions in a thin specimen.   The methods  are  useful  in  determining  plane  strain fracture  toughness,  dynamic  plane-strain  crack initiation and arrest fracture toughness,  the J-Integral for the material, and the fracture mode transition behavior when the specimen thickness and volume is smaller than previously thought necessary.
