No. of bitstreams: 1 Tivelli_Erick_M.pdf: 5369905 bytes, checksum: b9254f481c50f8e409adfc4b024d1c79 (MD5) Previous issue date: 2012 / Resumo: O presente trabalho analisou experimentalmente a utilização de latas de alumínio como absorvedor de energia de impacto. Foram realizados ensaios de compressão estáticos e dinâmicos objetivando correlacionar as deformações das latas com a energia absorvida. Foram analisadas a influência de fatores como, preenchimento da lata (ar ou vermiculita expandida) e disposição do arranjo para receber o impacto nas condições de latas separadas ou agrupadas. O levantamento das características da deformação que estão vinculadas com a absorção do impacto permitem especificar o tipo ideal da estrutura a ser impactada para diferentes aplicações. Os resultados do estudo viabilizaram a utilização das latas de alumínio, na condição de absorvedores de energia com deformação controlada, em barreiras de trenó de impacto / Abstract: The present study examined experimentally the use of aluminum beverage cans as absorbing impact energy elements. Crushing tests were performed aiming to correlate static and dynamic deformations of the cans with the energy absorbed. The study evaluated several conditions for forming a barrier capable of absorbing impact energy during impact tests on the sled. Static and dynamic crushing tests were performed aiming a better understanding of the behavior of the cans in such situations, and also analyzed the influence of factors such as filling the can (air or expanded vermiculite) and arrangement of the impact barrier, this tested the can as a honeycomb and in separate conditions. The study of the characteristics of deformation that are linked to allow the absorption of impact specify the ideal type of structure to be impacted for different applications. The results obtained in this work enabled the use of aluminum cans as agents of energy absorbers for the sled test / Mestrado / Materiais e Processos de Fabricação / Mestre em Engenharia Mecânica
