Strain Path Effect On Austenite Transformation And Ductility In Q&P 1180 Steel, Jeffrey Grant Cramer
Strain Path Effect On Austenite Transformation And Ductility In Q&P 1180 Steel, Jeffrey Grant Cramer
Theses and Dissertations
The ductility of Q&P 1180 steel was studied with regard to retained austenite transformation under different strain paths. Specimens were tested in uniaxial tension in a standard test frame as well as in situ in the scanning electron microscope (SEM). Then digital image correlation (DIC) was used to compute the effective strain at the level of the individual phases in the microstructure. Stretching experiments were also performed using limiting dome height (LDH) tooling, where specimens were strained in both biaxial and plane strain tension. The experiments were done incrementally, for each strain path, and the retained austenite at each level …

In Situ Characterization Of Voids During Liquid Composite Molding, Brock Don Zobell
Theses and Dissertations
Global competition is pushing the composites industry to advance and become more cost effective. Liquid Composite Molding or LCM is a family of processes that has shown significant promise in its potential to reduce process times and cost while maintaining high levels of part quality. However, the majority of research and information on composite processes have been related to prepreg-autoclave processing which is significantly different than LCM. In order for LCM processes to gain large scale implementation, significant research is required in order to model and simulate the unique nature of the resin infusion process. The purpose of this research …
