Development of Orthotropic Damage Model for Crush Simulation of Extruded Aluminum Member

Article of Honda R&D Technical Review Vol.19 No.1

Summary

It is well known that an extruded aluminum member has the different mechanical characteristics between the axial direction and the normal direction. It is important to consider the extruded direction dependence of mechanical characteristics in evaluating the energy absorption performance of the extruded aluminum member at non-uniform loading directions. For simulating such an orthotropic mechanical characteristic, the simple orthotropic damage model was proposed with the simulation method. The test specimens were cut out of the axial aluminum member in the axial and normal directions. The tensile, three-point bending and mixed-mode fracture tests were conducted in order to obtain the orthotropic characteristics. The simple orthotropic damage model was proposed and applied to the crush behavior of the extruded aluminum member. The load displacement curve and damage zone development were compared with those obtained by the experiments. As a result, the usefulness of the orthotropic damage model and simulation methods were validated.
