As is customary in this sort of problem, we will seek to position the support such as to minimize the 'strain energy' U of the loaded beam, which is a measure of its 'flexibility'. We have not discussed the notion of strain energy in a structure until now so we will start with ...
As the governing energy balance demonstrates, air beam bending is dependent upon strain energy and PV-work (air compressibility). The relative importance of these terms will vary with pressure, volume changes and shear deformations. To this point, a swatch of uncoated plain-woven fabric was ...
In general, strain-induced gradients of energy gaps create a force on (neutral) excitons that pushes them towards the regions with the smallest energy gap. In direct gap semiconductors, this area corresponds to that of maximum tension. Hence, the strain pattern generated by simply poking a sheet...
wherein illumination with infrared radiation decreases the conduction26,27. In the cases of Ge and Si, minority carriers are optically freed by light with photon energy well below the semiconductor bandgap, which enhances the recombination process with the majority carriers and thus reduces...

Rather than the stiff and incompressible interlayer used, a more ‘… compliant and compressible interlayer would increase the duration of impact, allow time for absorption of the kinetic energy, and reduce the strain energy of the underlying core.’ Very similar far-field deformations were seen ...

The 'Effect of Strain' refers to the quantification of the interaction energy among carbon impurities based on the distribution of strain in a given configuration. It can be defined by comparing the total energies of the clean surface and the system with carbon impurities in different configurations...
Surface strain-hardening of iron alloys with an intense pulsed electron beamResults are presented from study of surface strain-hardening and measurements of the structure of carbon (St. 45, U7A, 40Kh) and alloy (R6M5, Kh6VF) steels subjected to surface fusion by pulsed electron beams with ...
