Micromechanical fatigue experiments for validation of microstructure-sensitive fatigue simulation models

Microstructure-sensitive investigation of magnesium alloy fatigue

Microstructure-sensitive Fatigue Modeling of Medical-grade Fine Wire

ACKNOWLEDGEMENTS This work would not have come to fruition were it not for the assistance and support I received from a great many people. I would like to express my thanks to my advisor, Dr. Richard Neu for providing direction throughout the research process, and for his expertise and helpful advice. I would also like to thank the members of my committee, Dr. David McDowell and Dr. Markus Reit...

Fiber Microstructure and Fatigue

Strong fibers can fail at low stresses under cyclic loading. This phenomenon, which is called cyclic fatigue, occurs to an unexplained extent only when part (or all) of the fiber is compressed or twisted for some fraction of the strain cycle. Industrial yarns used in rubber, a 2 MMM lb. annual market in which USA fiber producers are highly competitive, must retain a maximum fraction of their in...

Fatigue Failure and Damage Analysis of an Anti-roll Bar Subjected to Fatigue Experiments

The available fatigue theories have been examined using simple specimens subjected to bending or tension-compression loads. Therefore, the stress fields have been generally one or two dimensional. Anti-roll bar is a component belongs to the suspension system of the vehicles. In spite of having simple circular section, due to the having several curvatures, this component experiences a three-dime...

a study on thermodynamic models for simulation of 1,3 butadiene purification columns

attempts have been made to study the thermodynamic behavior of 1,3 butadiene purification columns with the aim of retrofitting those columns to more energy efficient separation schemes. 1,3 butadiene is purified in two columns in series through being separated from methyl acetylene and 1,2 butadiene in the first and second column respectively. comparisons have been made among different therm...
