Cement Changes and their Effects on Shrinkage and Durability of Concrete
(North Dakota State University, 2018)In this work, the effects of different cementitious combinations on drying shrinkage and durability of concrete are investigated. Shrinkage is caused due to loss of water from concrete due to evaporation. Cement paste is ... -
An Investigation of Mechanics of Collagen and Fibril in Bone and Interactions in Swelling Clays: A Molecular and Multiscale Modeling Study
(North Dakota State University, 2012)A fundamental study of the mechanics at the molecular scale and bridging it to the continuum level through multiscale modeling is the focus of this work. This work investigates how the material properties of nanoscale ... -
Characterizing the Aging-Driven Degradation Rate of Electrical Contact Resistance and Mechanical Integrity of Plastic-Encapsulated Au/Al Wire Bonds
(North Dakota State University, 2019)Gold-aluminum interconnect is an integral part of conventional chip packaging. The gold-aluminum interface deteriorates during the operation of a device due to the formation of gold-aluminum intermetallic compounds. Spatial ...
