Show Me: Making An Impact With Sandwiches

Devdas Pai, William Craft, Ajit Kelkar, Sunil Shenoy, Ronald Bolick North Carolina A&T State University


Research in the transportation industry is largely driven by the need to cut costs and weight and to develop structures with better impact absorption capabilities. Metal and/or composite honeycomb core materials sandwiched between metal or composite end plates have been used in high performance, high-stake aerospace structural members, and they hold a promise that sandwich structures can be made which are light, cheap, and so energy absorbent that they will revolutionize common ground transportation systems.

NC A&T State University has a number of grants involving research into impact damage including impact behavior of sandwich structures. The authors feel that this research is sufficiently mature and important so that impact experiments should be added to our laboratory sequence within the department. Research investigations of these materials in our labs involve static and dynamic testing including shear testing or impact testing, and it is relatively simple to include the important attributes of impact testing as a laboratory experiment. Motivating factors for us in developing new impact experiments include:

• providing our students with additional information on how to design (impact) experiments.

• enhancing our current educational content on data acquisition systems for dynamic events, and

• educating our graduates in an important technology for the 21st century. We feel that knowledge of impact phenomena and testing is an important modern design methodology.
