Modeling and Prediction of Ground Shock Induced by Penetrating Weapons in Spatially Random Geologic MediaSBC: Thornton Tomasetti, Inc. Topic: DTRA04009
We propose a stochastic-finite-element based methodology to address these requirements: (i) Characterize material variability; (ii) Quantify corresponding ground-shock variability; and (iii) Design instrumentation plan. The site is discretized into N finite-elements; rock properties over this domain are characterized as the components of an N-vector stochastic field. The probabilistic characterist ...SBIR Phase I 2005 Department of DefenseDefense Threat Reduction Agency

ADVANCED STRUCTURAL MATERIALS USED IN THE FABRICATION OF SUBMARINES CAN SUSTAIN LARGE STRAINS DURING THE FORMATION PROCESS CAUSED BY EXPLOSIVE LOADINGS. THE COMPUTATIONAL SOLID MECHANICS COMMUNITY HAS RECENTRLY RECOGNIZED SERIOUS SHORTCOMINGS IN CALCULATIONS USING MATERIAL MODELS IN THIS LARGE STRAIN REGION. BECAUSE OF THE IMPORTANCE OF CALCULATIONS IN UNDERSTANDING THE SHOCK RESPONSE OF SUBMARINE ...SBIR Phase I 1989 Department of DefenseDefense Threat Reduction Agency
