Abstract

Three different solutions for orthotropic, beam-like fracture specimens were compared in the current work. A beam theory-based approach was developed previously by the author. Another solution based on refined plate theory was also considered. Finally, equations based on a numerical calibration technique were utilized as a third solution. These solutions were extended for the case of composite double-cantilever beam, end-loaded split and single-cantilever beam fracture specimens. All the three solutions give reliable expressions for the double-cantilever beam. In contrast for the end-loaded split and the single-cantilever beam coupons the three models give quite distinct results, especially for the mode ratio of the single-cantilever beam specimen.
