CTA #30. Flexural Bond Performance
1975Investigates the development of flexural bond in short span hollow-core slabs under ultimate flexural loads. A simple criterion is proposed, on the basis of 32 tests, for assurance that the units will achieve or exceed the limiting steel tension specified by ACT 318-71.

Flexure mounts for high-performance astronomical lenses
SPIE Proceedings, 2006We have developed practical, high performance flexure mounts for large astronomical lenses in the Binospec spectrograph. Flexure mounts are an attractive alternative to the widely used elastomeric lens mounts when high axial stiffness is a priority and coupling fluids are incompatible with elastomers.

The performance of a linear compressor with triangle flexure bearings
AIP Conference Proceedings, 2012This paper reports the performance of a self-fabricated moving coil linear compressor at Zhejiang University. The efficiency of this compressor is tested by an RC load method. From experimental results, its resonant frequency is below 30Hz. When combined with a pulse tube cryocooler (PTC) working at 40Hz, the minimum temperature is 49.1K; the cooling ...

Performance of small arrays of flexural disk transducers
The Journal of the Acoustical Society of America, 1976Trilaminar disk elements of small aperture (a = 34 mm) have been used in compact four- and six-element arrays for 2.4-kHz resonant frequency projectors with improved performance over single balanced pair (two-element) projectors of larger (a = 54 mm) elemental aperture.

Flexural Performance of RC Elements with FRP Reinforcement
Composites in Construction, 2001In the field of fiber reinforced polymer (FRP) reinforced concrete (RC) structures most of the available research works relate to the flexural behaviour. This paper covers the main issues affecting the flexural behaviour of FRP reinforced members: the most significant experimental results obtained from several researchers are summarized and provisions ...

Testing Passive Components for Flexure Crack Performance
SMTA International, 2007ABSTRACT Surface mount capacitors are used extensively in harsh automotive applications. In addition, the assembly processes for manufacturing the electronic systems can often lead to high stress on the crack-sensitive passive components. The typical mode of failure is a flex crack, which can often leads to a “short” failure.

Fatigue Performance in Flexure of Fiber Reinforced Concrete
ACI Materials Journal, 1998An experimental investigation of the behavior of fiber reinforced concrete under cyclic flexural loading is presented. One type of polypropylene and two types of steel fibers in two different volume concentrations are studied. Load-deflection response is obtained for constant amplitude fatigue loading as well as for static loading.

Performance of velocity sensor for flexural wave reduction
AIP Conference Proceedings, 1996This paper presents the analysis (mathematical modeling) for the reduction of flexural wave (structure‐borne) noise that is generated by a line force on a steel plate. The steel plate is covered with a baffle (elastomer layer) to reduce the flexural wave noise.

Flexural performance of lightweight reinforced-concrete slabs
Proceedings of the Institution of Civil Engineers - Structures and Buildings, 2016Recent advances in high-performance/high-strength lightweight concrete (HP/HSLWC) have had limited application in structural construction because of the lack of design and construction guidelines and concerns about material properties and their impact on performance.
