The objective of this paper is to confirm the usefulnessof the proposed method of determination for generalized stress intensity factors (GSIFs) of sharp V-notched plates under transverse bending basedon Kirchhoff plate theory. First, by using the eigenfunction expansion method, singular strain fields in the neighborhood of the V-notch including the non-singular terms are derived. Second, using these strain fields, a theory of determining the GSIFs is presented under the condition of mixed mode loading. Finally, following the method, experiments on the specimens with various notch angles were performed for the mode I loading condition by using strain gages. The finite element analysis is also carried out to compare with the experimental results. The both results show good agreement between them.
