Dynamic Response of Concrete and Concrete Structures
Abstract
This report describes the first-year activity of a three-year research program whose objectives are to (1) Develop a loading function for close proximity explosions, (2) Determine dynamic strength properties for selected types of concrete, and (3) Incorporate the strength properties so determined into a localized failure criterion for reinforced concrete, (4) Use a structural analysis elastic/plastic finite element computer program to determine localized response for a concrete/steel finite element mesh, and (5) Combine all of these into a simple structural analysis program to determine response of underground structures to localized impulsive loads. A new Kolsky Bar System (Split Hopkinson's Bar) is being built to test concrete specimens up to 3 inches in diameter. A pilot program testing 0.75-inch diameter specimens in an existing Kolsky Bay System has shown a linear dependence of the unconfined compressive strength of mortar on the strain rate at the maximum stress. The pilot program has been useful for guiding the design of the new larger system.
