Probabilistic Engineering Analysis Using the NESSUS Software
Overview The ability to quantify the uncertainty of complex engineering structures subject to inherent randomness in loading, material properties, and geometric parameters is becoming increasingly important in the design and analysis of structures. Probabilistic analysis provides a means to quantify the reliability of complex systems in such areas as aerospace and automotive industries. Since structural analysis predictions are often based on the results of commercial Finite EleMent (FEM) programs (e.g., ABAQUS, ANSYS, and MSC/NASTRAN), probabilistic analysis methods must be linked to such programs to achieve useful reliability results. The NESSUS?? probabilistic analysis software combines state-of-the-art probabilistic analysis algorithms with general-purpose analysis packages to compute the probabilistic response and the reliability of engineering structures. In this paper, the NESSUS capabilities are presented and demonstrated for several application problems.
