Knowledge Base Repository
In addition to research papers, the Design Society is developing several valuable resources for those interested in the study of design. These include a repository of PhD theses, a library of case studies and transcripts of design activities, and an archive of our newsletters.

Abstract:
Experimental and numerical studies of ribs reinforced extruded aluminum column subjected to axial crush were carried out and results were compared with that of empty column. The Outcomes of numerical study were found to be in good agreement with the experimental results with the variations of 5–8%. Analysis has been carried out to study the effect of crushing rates and material nonlinearities on the crush characteristics. Results show that distance between the ribs plays a vital role in modifying the energy absorption capacity of structure by 50% with reduction in initial peak force by almost 5–7% as compared to empty extruded aluminum column for a given crushing distance.
