Mechanical Properties of a Material at Ultrahigh Strain Rates Induced by a Laser Shock Wave

摘要

In this study, the dynamic strength of the AMg6M aluminum alloy at high strain rates is investigated. A method of determining the time when spallation occurs in an opaque material is developed. It is shown that the material is deformed and destroyed through different mechanisms depending on the strain rate. The ultimate value of the dynamic strength of the material under investigation is measured.
