“Low-Deflection Portable Concrete Barrier” earned the Transportation Research Board’s (TRB’s) K. B. Woods Award for its authors Roger P. Bligh, Nauman Mansoor Sheikh, Dean C. Alberson, and Akram Y. Abu-Odeh of the Texas A&M Transportation Institute (TTI). Read the press release.
The paper, “Application of a Precast Concrete Barrier Adjacent to a Steep Roadside Slope,” was the 2010 winner of the Practice-Ready Paper Award sponsored by the Transportation Research Board’s Design and Construction Group. This award is given each year to an outstanding published paper that is judged to have the best potential for immediate implementation in the design and construction of transportation facilities.Read the press release and an article that appeared in a 2007 edition of the Texas Transportation Researcher.

Post Doctoral Research Associate Chiara Silvetri recently published an article titled “Investigation of LS-DYNA® Modeling for Active Muscle Tissues that appeared in the EA Information Engineering Journal newsletter.
This study is aimed at investigating and comparing one-dimensional and three-dimensional finite element models of active muscle tissue. Skeletal muscle is a very complicated biological structure to model due to its non-homogenous and non-linear material properties as well as its complex geometry. Additionally, forces generated from muscle activation are directly related to the muscle length and contraction velocity. Finite element discrete Hill-based elements are laregely used to simulate muscles in both passive and active states. There are, however, several shortfalls to utilizing one-dimensional elements, such as the impossibility to represent muscle physical mass and complex lines of action.
