Abstract:

The first part of the document presents results of shock tests on rectangular steel beams. The constants of a moment-curvature relationship, which includes rate effects, are related to experimental data. The second part presents a relationship between material parameters obtained from tension- compression tests to those in the moment-curvature equation. The third part presents theoretical response of a viscoplastic cantilever beam to a shock input.
