Scaling issues in dynamic fragmentation

PDF Version Also Available for Download.

Description

A set of relations which would allow the experimental results of impact fragmentation experiments conducted under the controlled environment of a testing laboratory to be confidently scaled to realistic system dimensions would be an effective tool in the developments toward a predictive capability in full scale applications involving fragmentation. Here some of the issues governing scaling relations in dynamic fragmentation are discussed. Dimensional arguments are pursued. Some of the consequences indicate that fragmentation scaling relations are dependent on the specific material properties and mechanisms governing the fragmentation process. Transitions in functional forms of the scaling relations can be expected under ... continued below

Description

A set of relations which would allow the experimental results of impact fragmentation experiments conducted under the controlled environment of a testing laboratory to be confidently scaled to realistic system dimensions would be an effective tool in the developments toward a predictive capability in full scale applications involving fragmentation. Here some of the issues governing scaling relations in dynamic fragmentation are discussed. Dimensional arguments are pursued. Some of the consequences indicate that fragmentation scaling relations are dependent on the specific material properties and mechanisms governing the fragmentation process. Transitions in functional forms of the scaling relations can be expected under conditions in which fragmentation mechanism transitions occur in complex engineering materials. Some computational simulations and experimental impact fragmentation results are examined.
