Abstract: A transient response model is developed for collectors whose dynamic behavior is controlled predominantly by the absorber surface and heat-transfer fluid. Such collectors can be described adequately ...

Abstract: This paper presents the results of a preliminary analysis of the branching behavior of a horizontal subsurface crack subjected to a moving compressive surface load. The purpose of the analysis ...

Abstract: This paper demonstrates the capability to perform three-dimensional computations for explosive-metal interaction problems with complex sliding surfaces. An analysis is performed for an explosive ...

Abstract: This paper proposes a simple reduced-order model for a general flexure-guided piezoelectrically actuated nanopositioner and employs it to derive the upper limit of achievable bandwidth for a specified travel range. It is ...

Abstract: The vitreous body is a transparent gel occupying the posterior segment of the ocular globe. In diseased states, vision is obscured by haemorrhage or opacity or may be lost because of retinal ...

Abstract: An exact solution is obtained for the behavior of an ideal elasto plastic hollow sphere which is thermally stressed by a slowly increasing temperature difference between the inner and outer ...

Abstract: The results of ASHRAE 93-77 instantaneous and all day tests for two Sunpak™ evacuated-tube collectors are presented and discussed in terms of a simple dynamic response model and a biaxial ...

Abstract: Studies of the fracture behaviors of strain-rule sensitive materials suggest sharply notched impact-type toughness evaluations are fast enough for adiabatic conditions at the crack border and are ...
