Experimental Investigation and Computational Modeling of Shock Response of Cementitious Materials
Abstract
This AASERT was linked to the parent AFOSR project AFOSR F49620-96-1-0393, to develop fundamental knowledge on shock response and geo- and cementitious materials, through a coordinated, multidisciplinary research effort. The AASERT research focuses on systematic experimental investigation, paralleled with physically-based micromechanical modeling and computational simulation of the shock response of advanced cementitious materials. By collaborating with Eglin and Tyndall Air Force Base, fundamental contributions were made toward a solution to this class of problems. A series of quasi-static and dynamic experiments using the existing state-of-the-art material testing and novel recovery Hopkinson facilities at UCSD's CEAM. Damage initiation and evolution was systematically documented, using material characterization techniques. Based on these observations, physically-based models which capture the essential features of the process of damage evolution were developed for computational simulation. These models will be cast into a framework suitable for implementation into large-scale computer programs and will be checked against independent experiments.
