Interaction Between Webs and Rollers in Roll-to-Roll Manufacturing Process Machines
(2019-05-01)
A web can be defined as a continuous flexible strip which is supported, guided and propelled by rollers. The work presented here studies the steady state behavior of the web between rollers and treated the web span as beam ...
Measurement and analysis of residual stresses in zirconia dental composites using micro X-ray diffraction
(2010-05)
Due to their aesthetic value and high compressive strength, dentists are utilizing ceramics as a material of choice for dental restorations. Among ceramics, zirconia provides high toughness and crack resistance. Residual ...
Study of frost growth on heat exchangers used as outdoor coils in air source heat pump systems
(2011-05)
Scope and Method of Study: During winter heating operation, the outdoor coil of a heat pump acts as an evaporator and when the ambient temperature is near freezing, the moisture in the atmospheric air freezes on the coil ...
Injection molded poly(ethylene terephthalate)-graphene nanocomposites
(2015-05)
Polymer nanocomposites are known for their superior properties (mechanical, thermal, etc.) compared to conventional composites. Nanoscale reinforcements are used to make such composites as they have fewer defects and higher ...
Study of Bubbly and Annular Flow Using Quantitative Flow Visualization
(2019-05-01)
Multiphase flow phenomena in bubble columns and annular pipe flow were experimentally studied using quantitative flow visualization. The bubble column work was divided between studies on the operation regime within a sparged ...
Structural Evolution During Spark Plasma Sintering, Oxidation and Crystallization of Iron-Based Metallic Glass
(2019-05-01)
Metallic glasses are a novel class of amorphous materials that have diverse potential applications due to their superior mechanical, electrochemical and tribological properties as compared to their polycrystalline counterparts. ...
Closed cycle propulsion for small unmanned aircraft
(2015-07)
This study evaluates the merit of closed cycle propulsion systems for use in unmanned systems. The complexity and added weight of closed cycle engines is offset by benefits in high altitude performance, operation in polluted ...
Honeycomb in hybrid composite armor resisting dynamic impact
(2015-07)
Behind Armor Blunt Trauma (BABT) is an emerging problem in body armor due to excessive deformation resulting from projectile impact. A potential to reduce BABT has been identified by incorporating a honeycomb layer in a ...
Ice Accretion on Small Unmanned Aircraft
(2019-07)
Aircraft icing is an important and complex problem. Small unmanned aerial systems are becoming increasingly common in high quality operations. The hazards of icing on these smaller aircraft are significant and primarily ...
Effects of ion irradiation on the microstructure and mechanical properties of titanium-based metallic glasses
(2019-08)
Metallic glass specimens with a nominal composition of Ti₄₀Cu₃₄-ₓPd₁₄Zr₁₀Sn2Siₓ (at.%), where x = 2, 3, and 5, were subjected to annealing and/or ion irradiation and their microstructure and mechanical properties were ...
