Stephanie Pitts focused on stabilizing the CompositePowerLawCreepStressUpdate module in the idaholab/moose repository by addressing a failing documentation test and enhancing model robustness. She corrected a documentation file path to ensure alignment between the module’s documentation and its actual behavior, reducing the risk of future regressions. Stephanie also introduced a new robustness test that validated phase-dependent power law creep behavior under mixed plasticity rules, directly improving test coverage and model reliability. Her work leveraged C++ for module development and Markdown for documentation, demonstrating depth in material modeling, solid mechanics, and testing while contributing to the repository’s overall maintainability.
