Service Life Prediction Models to Predict Building Skin Failures

October 1, 2018
Author(s)
Christopher C. White, Donald L. Hunston, Adam L. Pintar
Determination of the in-service performance and failure of a building envelope material exposed to outdoor weathering has been a significant research goal for the last 100 years. Typically, estimations of the time to failure or durability of a material is

Fundamentals and characterizations of scratch resistance on automotive clearcoats

September 11, 2018
Author(s)
Li Piin Sung, Linqian Feng, Nadia Benhamida, Pierre Morel, Andrew T. Detwiler, Jon M. Skelly, Leslie T. Baker, Deepanjan Bhattacharya
As original equipment manufacturers (OEMs) strive to deliver improved coating performance with a sustainable footprint, opportunities for innovation are emerging, particularly on improving mechanical properties, appearance, and solids content. Resistance

Influence of wind tunnel test duration on wind load factors

August 17, 2018
Author(s)
Dat Duthinh, Adam L. Pintar, Emil Simiu
A methodology is presented for calculating the uncertainty associated with the estimation of peak pressure coefficients from wind tunnel test records of various lengths, and how this uncertainty affects design wind effects. Investigation of time series

Development of Airborne Nanoparticle Exposure Modeling Tools

July 27, 2018
Author(s)
William S. Dols, Andrew K. Persily, Brian J. Polidoro
Engineered nanoparticles (ENP) are being used in many applications including consumer products. There are many different means by which ENPs may be incorporated into these products (freely- dispersed, embedded, reactive or passive) which can impact the

Simmering Sauces! Elevated Formaldehyde Concentrations from Gas Stove Burners

July 22, 2018
Author(s)
Dustin G. Poppendieck, Mengyan Gong
Formaldehyde is listed as a human carcinogen, and can be formed as a primary by-product during combustion processes. Past studies have not detected elevated formaldehyde concentrations from gas stoves, perhaps due to the time averaging nature of previous

Quantifying Wind-Driven Firebrand Production from Roofing Assembly Combustion

July 16, 2018
Author(s)
Samuel L. Manzello, Sayaka Suzuki, Tomohiro Naruse
Large outdoor fires present a risk to the built environment. Examples often in the international media reports are wildfires that spread into communities, referred to as Wildland-Urban Interface (WUI) fires. Other examples are large urban fires including
