XML Database Structure – A Work in Progress

Project Description

This project will develop an aggregated database of creep and creep-fatigue validation data from existing datasets for P91 steel and 316 stainless steel. The database will be used to benchmark the creep and creep-fatigue models results obtained into a variety of finite element models, evaluate and test the performance of the models with respect to experiment uncertainty and the repeatability and stability of extrapolations across boundary conditions and regimes, and perform computational validation and assessment of creep and creep-fatigue constitutive models for standard and non-standard loading conditions.

Project Benefits

Expansion of the University of Texas at El Paso’s capability to conduct experimental research that replicate the extreme boundary conditions experienced by modern and advanced materials. Using the resulting guidelines developed, a component designer will be able to easily select the best constitutive model(s) and experimental datasets for intended designs.
