Abstract Scope |
Dynamic tensile failure, or spall failure, is an important property for understanding a materials’ response to high-strain-rate deformation and shock-wave compression. Spall strength measurements have been performed on many metals and alloys, however, the physical properties that influence the spall strengths of this broad category of materials are not well understood. The measured spall strengths for metals and alloys have been obtained from literature and tabulated for examination through data analytic techniques. The spall strength values have been correlated to other, more easily accessible properties that are expected to control spall behavior, such as yield and tensile strengths, elastic moduli, and other physical material properties – referred to in this work as “proxy properties.” These proxy properties have been used to establish design guidelines that can predictively classify a metal’s spall strength as high or low. |
