A numerical method for calculating the strain rate intensity factor [PDF]
, 2015 The strain rate intensity factor is the coefficient of the leading singular term in a series expansion of the equivalent strain rate in the vicinity of maximum friction surfaces. In the case of rigid perfectly plastic solids, the maximum friction law postulates that the friction stress at sliding is equal to the shear yield stress.

Comparative analysis of the DFB fiber laser and fiber-optic interferometric strain sensors [PDF]
, 2007 The DFB fiber laser strain sensor is shown to provide an improvement in the minimum detectable length change by a factor of 275 at 2 kHz for an applied strain when compared with an interferometric sensor interrogated by at equivalent DFB laser.

Indicators of intensive care unit capacity strain: a systematic review [PDF]
Critical Care, 2018 Abstract Background Strained intensive care unit (ICU) capacity represents a fundamental supply-demand mismatch in ICU resources. Strain is likely to be influenced by a range of factors; however, there has been no systematic evaluation of the spectrum of measures that may indicate strain on ICU capacity.

Measurements of Strain-Rate Distributions on Material After Shpb Impact
Engineering Transactions, 2014 We have proposed a sophisticated novel method of the SHPB experiment to measure the local strain-rate distributions on a surface of the specimen by using mechanoluminescent materials combined with a high-speed camera and an image intensifier.

Manipulating fluorescence intensity with mechanical strains
Materials Research Express, 2015 In this paper we show that the fluorescence of rhodamine 6G (R6G) can be manipulated by applying mechanical strains to gold nanoparticles (GNs) sandwiched in graphene/GNs/polydimethylsiloxane (graphene/GNs/PDMS) structure. The fluorescence intensity of R6G on the graphene/GNs/PDMS sample shows a gradual increase with the mechanical strain. However, the
