Development of Aluminum Honeycomb Model Using Shell Elements

This paper describes a new finite element modeling method of aluminum honeycomb using shell elements. It is our new modeling method that cell size of honeycomb structure is enlarged to keep minimum mesh size, and compressive strength is controlled by thickness of shell elements. New modeling was applied to an offset deformable barrier model, and full vehicle crash analysis was performed. The result of offset frontal collision analysis with a new honeycomb model showed much better correlation with test results than with modified material type-126 solid elements.
