Abstract Scope |
Metal foams play an important role in our lives and are used in a wide range of applications, from energy dissipation (safety) to energy saving (lightweighting). When metal foams are an integral part of a structure the mechanical characteristics and their response to external load need to be well understood. To facilitate a greater understanding, we have utilized lab-based dynamic computed tomography (CT) to visualize uninterrupted compression of aluminum metal foams and coupled these results to software simulations of the same samples. Two samples with different levels of cell density are tested, analyzed, and simulated. Data collected from the first sample is used to first analyze and determine material characteristics of the material, which are, in turn, applied as inputs in a compression simulation of a second sample. The second sample is also physically tested with dynamic CT to provide further verification and improvement of the simulation and modeling results. |
