Research is conducted for the development of probabilistic structural mechanics, solution/computational algorithms, and computer codes to quantify uncertainties associated with the parameters and variables required for structural analysis/design and thereby evaluate respective reliability and success. The research focuses mainly on developing probabilistic theories/models for predicting the thermomechanical behavior of propulsion structures made from high-temperature materials, which include metal matrix, ceramic matrix, and carbon-carbon composites. Two other areas include probabilistic simulation of the human factor and software reliability.

In addition, research is contemplated to demonstrate similarity and differences between probabilistic simulations and comparable simulations from (1) internal arithmetic, (2) chaos theory, (3) fuzzy logic/theory, (4) Taguchi methods, (5) design of experiments, and (6) neural networks, (7) structural optimizations, (8) genetic algorithms, and (9) error bounds. It is important to demonstrate that results from any or all of the above methods can be readily obtained by the appropriate use of only one method (e.g., probabilistic methods).
