Abstract:

	This project will explore the use of parallel processing computers to solve problems
in probabilistic structural mechanics (PSM) that arise in the assessment of reliability
of complex aerospace structures. PSM problems, solved by Monte Carlo simulation,
are inherently parallel and are ideally suited for solution on parallel computers.
Relatively little research, however, has been conducted in probabilistic structural
mechanics to exploit the power of these machines. The objectives of the Phase I effort
will focus on the evaluation, in a parallel computer architecture, of probabilistic
Monte Carlo implementation strategies, including pipelining (vectorization), concurrency
(multitasking), synchronization, and variance reduction techniques. While much of
the research in PSM over the last two decades has focused on basic theory development,
the next decade of research in computational PSM may open up a whole new class of
finite-element and dynamics problems to probabilistic structural analysis.

Potential Commercial Application:

Potential Commercial Applications: The solution of probabilistic structural mechanics
problems on parallel processing computers will provide direct guidance for probabilistic,
reliability-based analysis and design of space, defense, and critical commercial
structures.
