Peggi Clouston, associate professor in wood mechanics, and Sanjay Arwade, assistant professor in civil and environmental engineering, are creating the computational tools with a three-year, $300,000 grant from the National Science Foundation.
According to Clouston, SCL is a building material used extensively in North America in residential construction. SCL is created by layering dried and graded wood veneers or strands with waterproof adhesive to form long rectangular beams and other structural members.
SCL manufacturers want to make as strong a composite with the cheapest wood possible, such as waste wood or weed species, she says, but new products must be tested in a laboratory to determine their strength. That process can be time-consuming and costly, says Clouston.
Clouston and Arwade’s research is aimed at producing a quick and inexpensive analytical method that will accelerate the development of less costly or stronger wood products that could be used in major non-residential building projects such as shopping centers or schools, she says.
“By making the predictive capability widely available, this project marks a first step in advancing the practice of wood design to a state comparable to that of steel and concrete,” says Clouston. “Building products manufacturers and engineers will have a great interest in this.”
Along with economic advantages, she says, SCL offers significant environmental benefits because wood is renewable, recyclable, biodegradable and sustainable. “It takes less energy and creates less pollution to transform trees into wood products than it does to manufacture steel, concrete or plastic products,” says Clouston.
According to the researchers, the work will lay a scientific foundation for investigations into other wood products such as glue-laminated timber or plywood. Graduate-level course modules on wood composite modeling are part of their integrated plan for research and learning.

University of Maryland researchers contribute to historic detection of gravitational waves and light created by event
On August 17, 2017, at 12:41:04 UTC, scientists made the first direct observation of a merger between two neutron stars--the dense, collapsed cores that remain...
Seven new papers describe the first-ever detection of light from a gravitational wave source. The event, caused by two neutron stars colliding and merging together, was dubbed GW170817 because it sent ripples through space-time that reached Earth on 2017 August 17. Around the world, hundreds of excited astronomers mobilized quickly and were able to observe the event using numerous telescopes, providing a wealth of new data.
Previous detections of gravitational waves have all involved the merger of two black holes, a feat that won the 2017 Nobel Prize in Physics earlier this month....
Material defects in end products can quickly result in failures in many areas of industry, and have a massive impact on the safe use of their products. This is why, in the field of quality assurance, intelligent, nondestructive sensor systems play a key role. They allow testing components and parts in a rapid and cost-efficient manner without destroying the actual product or changing its surface. Experts from the Fraunhofer IZFP in Saarbrücken will be presenting two exhibits at the Blechexpo in Stuttgart from 7–10 November 2017 that allow fast, reliable, and automated characterization of materials and detection of defects (Hall 5, Booth 5306).
When quality testing uses time-consuming destructive test methods, it can result in enormous costs due to damaging or destroying the products. And given that...
