Nominal strength of quasi-brittle open hole specimens under biaxial loading conditions

One of the main purposes for an accurate strength prediction is to get a reliable design tool of a given structure. Since most of aircraft and aerospace structures contain many holes and are subject to multidirectional loading conditions, due to stress concentration, cracks will necessarily emanate...

The main goal of this work is to develop an analytical model able to predict the nominal strength and the failure envelope of isotropic quasi-brittle open hole specimens under biaxial loading conditions.
