Advanced Computational Solid Mechanics Laboratory (CSM)
Dr. George Z. Voyiadjis is the director of the Advanced Computational Solid Mechanics Laboratory (CSM). The CSM lab promotes research in materials science at LSU and in conjunction with other research facilities and teams around the world. By specializing in numerical analysis and experimentation at the nanoscale, CSM Lab pioneers the advancement of knowledge in this emerging area of science. Engineers, scientists, and technicians design new products for many reasons: to increase productivity and efficiency in the industrial process, to reduce the cost of manufacturing, to replace existing products that are aging, and to add new features that will benefit people's lives. Throughout the design process, selection and preparation of proper materials is crucial to achieving the desired result. As researchers understand more of how and why materials behave under real-world conditions, they can use that knowledge to create materials that are stronger, lighter, tougher, safer, etc. than those that are commercially available today. Building on the discoveries of past research efforts, this laboratory uses information from experiments with materials in conjunction with a powerful supercomputer to properly characterize material behaviors.

Driving Simulator Lab
The driving simulator lab hosts the LSU Driving Simulator, a full-sized passenger car (Ford Fusion) combined with a series of cameras, projectors and screens to provide a high fidelity virtual environment that offers a high degree of driving realism. It provides a one degree of freedom motion simulation to make a driver experience similar driving efforts as in an instrumented vehicle. Its open architecture software tools allows for data collection during simulation experiments, and creation of new networks and virtually an infinite number of simulation scenarios. Vehicle simulation makes it possible for inexpensive alternatives and sometimes impossible (unethical or safety implications) field tests to be undertaken in the lab. Research conducted in the lab include safety in work zones, examining driving behavior of distracted drivers, testing driver reactions and performance under varying categories of hurricane winds, and development of a connected-vehicles simulation test-bed. The lab is also capable of examining the effects of different levels of task complexity on visual fixation strategies and visual stimulus recognition, determining the effect of road signage, road type and other factors on driver performance, testing driver reactions and performance with new in-vehicle technology devices, and determining effects of fatigue and other distraction levels on driving performance. Such experimentations advances the state of the art in driving simulation, and do result in valuable findings that may save lives.
Structural Systems Testing Laboratory
Testing of structural components and subsystems is conducted using a 550-kip MTS tall load frame equipped with an MTS Flextest SE controller and National Instruments cDAQ-9178 data acquisition system with strain, thermocouple, voltage, and accelerometer modules. Measurement capabilities include strain gages and Linear Variable Differential Transformers (LVDTs). Hydraulic systems in the lab are powered with state-of-the-art pumps (MTS SilentFlo series). A variety of loading tips, spreader beams and custom fixtures are available.
In the near future (2014), the lab will be equipped with a strong reaction floor to allow testing components with a wider footprint. It will also allow setting multiple tests simultaneously.
Gulf Coast Center for Evacuation & Transportation Resiliency
The Gulf Coast Research Center for Evacuation and Transportation Resiliency, under the direction of Dr. Brian Wolshon, is a collaborative effort between the Louisiana State University Department of Civil and Environmental Engineering and the University of New Orleans' Department of Planning and Urban Studies. The theme of the LSU-UNO Center is focused on Evacuation and Transportation Resiliency in an effort to address the multitude of issues that impact transportation processes under emergency conditions such as evacuation and other types of major events. This area of research also addresses the need to develop and maintain the ability of transportation systems to economically, efficiently, and safely respond to the changing demands that may be placed upon them.

L.H. Bossier Asphalt Laboratory
The L.H. Bossier Asphalt Laboratory is used for undergraduate and graduate classroom demonstrations and laboratory classes. When not occupied for classes, the lab is used for student and faculty research involving the composition and qualities of different types of asphalt, and ways to improve its installation, function and longevity.
ETEC Hydraulics and Water Distribution Laboratory
The ETEC Hydraulics and Water Distribution Lab provides Civil and Environmental Engineering undergraduate students with an experimental and modeling facility where they can get hands-on experience in the real-time monitoring, control, and modeling of hydraulic systems. The lab, sponsored by Environmental Technical Sales, Inc., currently consists of a series of pipes in various diameters, valves, switches, flow meters and pressure gages that are all connected to two reservoirs for water distribution control problems. This pipe loop system can be configured to operate as independent individual loops, collectively as one unit, or in various configurations. Several PC-based computers are set up, some for running water distribution control and monitoring software and the others running monitoring software and hydraulic modeling software. The real-time monitoring and optimization software equips students with the ability to provide constant flow control according to changing demands, while monitoring main water lines, reservoir levels, water quality, etc. The software also enables continuous monitoring of water quantities and pressures. Extensive renovations are underway that include additional computer workstations to serve as a means to control, monitor, and model tracer movement through the system. Also, a connection system will be put into place to open the channel flume where small turbines will be located. The operation and monitoring of these turbines will also be done at these additional workstations.
Geotechnical Engineering Laboratory
The Geotechnical Engineering Laboratory is equipped with testing equipment for (a) geophysical monitoring: a signal generator (33509B,Agilent) for S-wave excitation, a high-voltage pulser (5077PR,Panametric) for P-wave excitation, a signal amplifier (3944, Krohn-Hite), and a digital oscilloscope (DSOX2024, Agilent) for acquiring transmitted waves, (b) high-pressure testing system: a high-pressure syringe pump which can control the pressure up to 5000 psi and the flow rate as slow as 0.001 mL/min, temperature controller, and (c) standard and specialized soil testing: the geotechnical engineering laboratories are equipped to conduct all the standard physical and engineering properties tests on soils including gradation, specific gravity, Atterberg limits, permeability, shear strength, compaction, and consolidation. One unique feature of the geotechnical laboratories is that posses two true cubical triaxial testing devices (for low and high pressure testing regiomes). These devices are fully equipped with data acquisition systems.
Louisiana Transportation Research Center (LTRC)
Since its creation by the legislature in 1986, the Louisiana Transportation Research
Center (LTRC) has grown to national prominence through its efforts to improve transportation
systems in Louisiana. The center conducts short-term and long-term research and provides
technology assistance, engineering training and continuing education, technology transfer,
and problem-solving services to DOTD and others in the transportation community.
The center, sponsored jointly by Louisiana State University and the Louisiana Department of Transportation and Development, is largely supported by funding authorized by the Federal Highway Administration. LTRC's goal is to merge the resources of state government and universities to identify, develop, and implement new technology to improve the state's transportation system. LTRC combines the efforts of DOTD and the state's universities to find innovative solutions to Louisiana's transportation problems.
