Abstract : The literature concerning the current state of the art in welding, rippling, and surface jetting due to impact (shock) loading by low velocity impact, hypervelocity impact, and explosive loading on many types of metallic and nonmetallic materials has been intensively studied. Efforts have been made to correlate the results of other researchers in this field, both theoretical and experimental, and to explain them by means of the results achieved in this investigation. A historical section is used to connect the original awareness of the phenomena associated with impact loading to the current results and analysis. An experimental section details the current results. Finally, the general and specific results of these and other investigators are analyzed and discussed, including the formation of ripples and welds at interfaces, the phenomena associated with these results, and the overall effects of impact loading upon the material properties. The appendix also details the theory behind the formation of waves and wavelike forms other than ripples in an impact loaded interface and includes a discussion of some of the natural ways that waves are created.
