ABSTRACT = {Fracture analysis is a problem playing a fundamental role in the fields of Aerospace Mechanics and 
Structural Mechanics. The paper deals with the analysis of the most essential among the fracture problems: 
the one-dimensional crack in a double cantilever beam. The report presents a reliable analytical method to 
correctly partition the energy release rates into pure fracture modes, appliable to both isotropic and 
composite beams with clearly known mechanical properties, subject to shearing or bending loads. The 
adopted strategy is based on the Timoshenko’s kinematic model and exploits the theoretical definition of 
the I and II pure energy release rate modes. Following this study, a promising analytical expansion of the 
outlined approach is introduced. The obtained, innovative method only requires the geometrical features of 
the beam for the partitioning of the energy release rate. The concluding pages of the paper uncover the 
underlying principles and complexities of the problem, presenting the development of a general analytical 
method for beams subject to any kind of load. All the proposed analytical methods have been extensively 
validated against numerous numerical solutions, proving themselves to be a valid alternative to 
computational expensive FEM codes.},
