Wisconsin Structures and Materials Testing Laboratory
About the lab
The Wisconsin Structures and Materials Testing Laboratory (WSMTL) provides UW students and faculty, as well as industry, access to equipment and technical support for testing of material samples and large-scale structural components. The purpose of WSMTL is to enhance the teaching and research experience of UW students through a variety of hands-on experimental testing techniques.
People who conduct research in the laboratory
As a multi-disciplinary facility, users of WSMTL include faculty from all departments within the College of Engineering. Faculty in the Department of Civil and Environmental Engineering are primary users of the structural testing equipment. Materials testing capabilities are utilized by faculty in Mechanical Engineering, Biomedical Engineering, Materials Science Engineering, and Engineering Mechanics.

Engineering student organizations such as Concrete Canoe, SAE Vehicle Teams, and Steel Bridge frequently use the testing capabilities within the lab.
As a service, the laboratory provides testing to the public and private organizations. This activity is conducted on a cost-reimbursable basis. In addition to fulfilling a service mission, service testing provides better utilization of test equipment, defrays the cost of maintaining equipment and operating the laboratory, and sometimes provides engineering students the opportunity to learn and practice their testing skills. Please see the Priority Policy Instructions below for more information.
WSMTL capabilities range from materials and structures testing to sound measurement, fatigue, in-field measurements, large-scale structure testing, and more. If you would like to discuss your testing needs, contact the lab.
Universal testing machines with capacities ranging from 50 lbs up to one million pounds in tension or compression. Screw-driven MTS load frames for large displacement quasi-static testing as well as high force and high cycle rate servo-hydraulic frames.
Free-standing actuators ranging from 3-kip to 200-kip capacities. Reinforced strong-floor and strong-wall with lab to accommodate a variety of structures.
Wide variety of accelerometers and state-of-the-art data acquisition equipment. Electro-dynamic shakers with force capacities ranging from 2 lbs up to 2,200 lbs. Our vibration testing and analysis capabilities include non-contact doppler laser vibrometry, modal analysis, structural monitoring, MIL-SPEC methods, and experience with non-linear structures.
Instrumentation and data acquisition with capabilities in excess of 20 channels. We have a wide variety of load cells and displacement sensors for instrumenting structures under test.
Our lab can provide assistance with transducer gaging, design, and calibration. We have expertise in mounting gages for materials testing, using gages for numerical and analytical correlation, and teaching students how to mount gages.
