... granular composites exist at several popular racing surfaces in the United States and around the globe as a replacement for traditional dirt surfaces. These synthetic materials are composed of sand, polymer fiber, and rubber particulate components bound together by a wax polymeric binder. Materials testing...

...Ihor Zanevskyy; Lyudmyla Zanevska Competition results in gymnastic vaults depend in great measure on testing and tuning of the springboard’s mechanical parameters, especially the stiffness. There are four empirical tests of the gymnastic springboard; one of them is a static test, and the three...

...Ross McCarthy; Gerardo Flintsch; Edgar de León Izeppi Skid resistance is a characteristic of a pavement surface that is critical to pavement safety. Skid resistance can be measured with different types of equipment, but because of the differences in the system configurations and the testing methods...

...Meredith McQuerry Heat transfer through clothing systems can mean the difference between life and death for first responders, such as firefighters, who perform intense physical activity in extreme environmental conditions. Total heat loss (THL) is a fabric level test method required by the National...

...Yun-Tsan Lin; Tsang-Chuan Chang; Kuen-Suan Chen Improving fitness levels is a key area of preventive medicine and plays an essential role in health promotion. Most organizations, constrained by time, manpower, and cost, conduct fitness tests on a random sample of the population in order to gain...

...J. Schuurmans The reliable measurement of characteristic force values from instrumented Charpy impact tests is considered of high importance at SCK•CEN in view of the “Enhanced Surveillance” of nuclear reactor pressure vessels. The previous development of instrumented strikers for the Toni MFL...

...C. Mahrenholtz; A. Sharma Tests on anchors and reinforcing bars in cracked concrete members with cyclically opening and closing cracks are carried out to study their performance under variable live loads and seismic loads. Cyclic crack tests are the most demanding and often decisive test series...

...Luis F. Sánchez-Heres; Jonas W. Ringsberg; Erland Johnson In mechanical characterization methods, the mechanical properties of multiple material test specimens are measured to determine the probabilistic characteristics of the material's properties through statistical inference. Several...

...Nemkumar Banthia; Sidney Mindess; Zhengwu Jiang The influence of feedback control on the measured flexural toughness of fiber reinforced concrete (FRC) remains elusive. Some tests such as ASTM C1609/C1609M-07 require closed-loop control, while others such as ASTM C1399/C1399M-10 are considered...

...Matthew S. Hoehler; Robert K. Dowell; Derrick A. Watkins This paper describes the construction, calibration and experimental validation of a test apparatus to measure axial and shear forces in anchors. Accurate measurement of anchor shear force has historically proven technically challenging...

...Zhengwu Jiang; Nemkumar Banthia The influence of specimen size on measured flexural toughness of fiber reinforced concrete (FRC) remains largely unknown. Towards this end, an experimental program was carried out where flexural toughness tests were performed on specimens of two different sizes using...

The data presented in this study will assist product and package designers to reduce damage in transit by using the recommended vibration test spectrums to evaluate products...

... crushes, 0.8 others, 0.2 tape failures, and 0.1 scuffs per shipment. Based on these results, a test protocol was developed to reproduce this damage. The test includes vibration testing, compression testing with an edge hazard, at drop onto a point hazard, tip-over test onto an edge hazard, and corner...

...N Banthia; S Mindess The major advantage of fiber-reinforced concrete (FRC) over its plain counterpart is in its improved energy absorption capability, or ‘toughness.’ There are currently several standard test methods available to characterize the toughness of fiber-reinforced concrete, but little...
