摘要

Engineers at Los Alamos National Laboratory (LANL) are currently developing thecapability to provide a reliability-based structural evaluation technique for performing weapon reliability assessments. To enhance the analyst's confidence with these new methods, an integrated experiment and analysis project has been developed. The uncertainty associated with the collapse response of commercially available spherical marine float is evaluated with the aid of the non-liner explicit dynamics code DYNA3D coupled with the probabilistic code NESSUS (Numerical Evaluation of Stochastic Structures Under Stress). Variations in geometric shape parameters and uncertainties in material parameters are characterized and included in the probabilistic model.
