Three-dimensional effects on the dynamic fracture determination of Al 7075-T651 using TPB specimens
چکیده انگلیسی

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 Opening 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.
