| Abstract: | Here we present a numerical analysis of three dimensional effects on the dynamic three point bending fracture tests on Al 7075 T651 alloy specimens performed in a modified Split Hopkinson Pressure Bar. Using the Finite Element Method implemented in a commercial code the whole experimental device has been modeled. Different thicknesses and initial crack to width ratio specimens are simulated at different impact velocities to study the possible effect on the Crack Mouth Open ing Displacement and, using a local stress fracture criterion, in the critical Stress Intensity Factor. The numerical results are compared with experimental results found by the authors. |
