Finite element studies of mechanical property testing by nanoindentation methods
Nanoindentation is a widely recognized method for characterizing the mechanical properties of thin films and small volumes. This dissertation reports the results of finite element analyses of elastic and elastic-plastic ...
Numerical study of thin-film flows and open-channel flows
A numerical procedure is developed capable of simulating gravity-driven film flows in two-dimensions. The moving boundary problem is handled through the ALE formulation. In the case of turbulent fluid flows, the two-equations ...
Average antiplane motion in an elastic solid containing a layer of randomly distributed cracks
The propagation of antiplane waves in an elastic solid containing a random distribution of cracks that are parallel to each other, and oriented at an arbitrary angle relative to the direction of the incident wave, is ...
Low Dean number flows in helical ducts of rectangular cross section
The flow in a helical duct is characterized by increased fluid mixing, accomplished by the inducement of a secondary flow in the plane normal to the helix centerline. Two independent phenomena interact to produce this ...
Degradation of optical properties in anodic coatings exposed to vacuum-ultraviolet radiation
Sulfuric acid anodized aluminum coating systems possessing a low ratio of solar absorptance to infrared emittance are susceptible to vacuum-ultraviolet radiation. Vacuum-ultraviolet exposure can degrade the coating systems ...
Instabilities in heated falling films: A full-scale direct numerical simulation
A thin liquid layer draining on a heated inclined plane is susceptible to long surface waves, and can either form waves and stay continuous or go through a rupture process leading to the formation of rivulets. It is of ...
