An investigation of methods for determining notch root stress from far field strain in notched flat plates.
Garske, John Charles
MetadataShow full item record
Notched flat plate specimens have been tested to examine Neuber's equation and other relations with respect to their application in the determination of stresses in the plastic range at the notch root when the far field strain is known. A nonlinear finite element solution has also been obtained for notched flat plates in plane stress to facilitate an evaluation of it as an analytical method for calculating the behavior of stresses at the notch root. Experimental results indicate that Neuber's equation is ten to twenty- five percent in error for the notch geometry, strain level and material behavior encountered in the present study. Finite element analysis results were in close agreement with experimental results.
