✦ Synopsis
An experimental method is proposed for fracture characterization of solid propeilams. Regarding non linear behaviour of such material, investigation is restricted to high loading rate conditions and J1, fracture criterion is computed. A tensile split Hopkinson bar device was WI up ;md fitted to experiments up to strain rate of 300 SC', hisymmetric samples of various crack length was tested allowing Jr, computation using Begley-Landes method. Results are then analysed and special attention is given to validity of L.E.F.M. assumptions in this case.
