Characterizing the Operation of a Dual-Fuel Diesel-Hydrogen Engine near the Knock Limit
(North Dakota State University, 2014)
A CAT C6.6 turbocharged diesel engine was operated in dual-fuel diesel-hydrogen mode. Hydrogen was inducted into the intake and replaced a portion of the diesel fuel. Hydrogen was added across multiple engine speeds and ...
Brain Tissue Mechanical Characterization and Determination of Brain Response under Confined Blasts Explosions
(North Dakota State University, 2015)
Mechanical experimental tests including stress relaxation, simple monotonic ramps, and impact loads were performed on porcine brain tissues to investigate the response of the brain under different loading scenarios. Linear ...
Theoretical and Experimental Studies of Droplets Wetting on Micronano-Fibrous Materials and their Applications in Oil-Water Separation
(North Dakota State University, 2013)
This research was aimed at the theoretical and experimental investigation of wetting behavior of immiscible droplets sitting on filaments and related applications in oil-water separation. This work consisted of three ...
Computational Investigation of Low-Pressure Turbine Aerodynamics
(North Dakota State University, 2015)
The design of today’s gas turbine engines is heavily reliant on accurate computational fluid flow models. Creating prototype designs is far more expensive than modeling the design on a computer; however, current turbulence ...
Stress-Function Variational Methods for Stress Analysis of Composite Laminates and Adhesively Bonded Composite Joints
(North Dakota State University, 2015)
Adhesively bonded composite joints (ABCJs) have been broadly used to connect multimaterials
and show their structural and economic advantages compared to traditional bonding
methods. However, robust methods are still ...
Mechanical Analysis of Polycarbonate/Polysiloxane Block Copolymers and Blends
(North Dakota State University, 2013)
Polydimethylsiloxane (PDMS) can be used to react with polycarbonate (PC) to generate PC-PDMS multiblock copolymers and PC/PC-PDMS-PC triblock blends to overcome the notch sensitivity of PC while maintaining its transparency. ...
Development of Biobased Composites of Structural Quality
(North Dakota State University, 2015)
Highly biobased composites with properties and costs rivaling those consisting of
synthetic constituents are a goal of much current research. The obvious material choices,
vegetable oil based resins and natural fibers, ...
Microwave Torrefaction of Natural Fibers for Incorporation into Engineering Thermoplastic Biocomposites
(North Dakota State University, 2015)
Little work has been done in the area of engineering thermoplastic biocomposites due to the increased processing temperatures which induce degradation of biomass. Torrefaction has been identified as an effective means of ...
A Micromechanical Procedure to Characterize the Effect of Interface in Fibrous Composites and Brain White Matter
(North Dakota State University, 2012)
A micromechanics computational algorithm for fibrous composites including fiber, matrix and interface is introduced to study the impact of interface on composite behavior. The domains are modeled by finite elements with ...
Potential Applications of Flax Fibers
(North Dakota State University, 2018)
There has been a substantial increase in the usage of natural-fibers and biodegradable polymers due to the needs of the environmental sustainability. The use of natural fibers is inclusive of wide range of applications in ...
