    Abstract

    Using a finite element model to generate compliance values, stress intensity solutions were developed for an edge cracked T-section in tension. The finite element model was developed specifically for T-section geometries with thin web sections. Several T-section geometries were analyzed. A limited set of experiments were performed to validate some of the finite element modeling using compliance specimens. The experimental results were in good agreement with the predictions made using the finite element model. Dimensional similarity was investigated and a set of dimensionless modeling parameters were identified.
