ABSTRACT: Autonomous vehicles lack a standardized mechanism for seamless cross-platform sharing of testing frameworks and evaluations of basic tasks. The ability to execute common tests on various hardware platforms is essential in order to be able to e

The Defense Threat Reduction Agency has expressed the need for waterborne transport and dispersion capability to compliment its existing models for Chemical, Biological, Radiological and Nuclear (CBRN) releases. DTRA's current capability is limited to the atmospheric transport of CBRN agents using the HPAC system. The objective of this proposed Phase I study is to couple Applied Science Associat ...

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 ...

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 ...
