"Under irreversible conditions an effective surface energy of plexiglas for notched bars deformed in three-point bending was measured. The various equations proposed for evaluating surface energy are described and values of surface energy obtained using these equations are reported for a variety of sample dimensions. A comparison has been made between the results obtained. The effect of different notch shapes, sharp V, square U and round, on calculated values and fracture characteristics are noted. The Griffith theory is shown to be valid for large crack dimensions"--Abstract, page ii.
