Several new roadside safety appurtenances that can be directly linked to the use of nonlinear finite element analysis with LS-DYNA are being installed along the nation's roadways. These advances can be attributed to FHWA's sponsored research program known as Centers of Excellence in DYNA3D Analysis. Some of the simulation efforts at the Midwest Roadside Safety Facility over the past 10 years are documented to help educate the roadside safety engineer and to promote the use of simulation. Noteworthy progress has been made in the use of LS-DYNA for the design and analysis of roadside safety hardware, and it is believed that a great deal more progress is possible.
