A Fracture Limit Diagram for Determining Hydrogen Embrittlement of Sheet under Multiaxial Loading Conditions
Abstract
The application of punch-stretch testing as a means of determining hydrogen embrittlement of sheet under multiaxial loading conditions is described. The results may be expressed in the form of a fracture limit diagram which identifies at fracture the principal strain components in the plane of the sheet for any multiaxial deformation path associated with a thinning of the sheet. As an illustration, a fracture limit diagram is reported for internally charged, commercially pure titanium sheet. The diagram clearly shows that the titanium is susceptible to hydrogen embrittlement under plane strain and biaxial loading paths even though no loss of ductility occurs in simple tension.
