Abstract:The issues of thermal softening and adiabatic shear failure, in dynamically compressed metals, are revisited through experiments in the Kolsky bar system. Various materials were compressed by singleand multi-step loadings and the results were analysed through a new approach to the issue of instability strain, which is based on the temperatures existing in the specimens just prior to the onset of instability. These temperatures are compared with the threshold temperatures, which mark the steep decrease in the s… Show more
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
