Abstract
Current personnel protection against blast often consists of multi-layered material systems utilizing a combination of rigid materials, such as ceramic plates, and soft materials such as compressible foams. A good understanding of the response of polymeric foams to blast loadings is essential to ensure better guidance in the development of protection equipment. There are multiple approaches currently in use for characterizing the response of foam to blast loading and these include shock-tube and free-field trials. The loading generated from a shock-tube is quite different from the one in free-field trials. However, shock-tube experiments are more practical and efficient than free-field trials. This paper presents numerical and experimental results, which show the responses of polymeric foams to these two different loadings. Using finite element method, the two types of loadings were modeled and reasonable agreement between the experimental and numerical results was obtained.
