This paper presents an experimental study of imperfection insensitive composite wavy cylindrical shells subject to axial compression. A fabrication technique for making cylindrical shells with intricate shape of cross-sections has been developed. A photogrammetry technique to measure the geometric imperfections has also been developed. The behavior of the wavy shells under axial compression was...

Sputtering was utilized to deposit polycrystalline Cu and CrN films sequentially onto Si(100) substrates, forming specimen assemblies in which predominantly ⟨111⟩ oriented Cu thin films of varying thicknesses were confined between Si and CrN. Cylindrical micro-pillars of CrN/Cu/Si(100)were fabricated through focused ion beammilling,with the interfaces either normal to the axial direction or at ...

The primary function of the disc is mechanical; therefore, degenerative changes in disc mechanics and the interactions between the annulus fibrosus (AF) and nucleus pulposus (NP) in nondegenerate and degenerate discs are important to functional evaluation. The disc experiences complex loading conditions, including mechanical interactions between the pressurized NP and the surrounding fiber-rein...

In this study, experimental study on six RC columns with different slenderness ratios under axial rapid loading was conducted to investigate the axial compression behaviour of RC columns considering the effect of strain rates. The failure pattern of the specimens and the relations of axial loading versus the axial deformation were described. From the test results, the specimens under static and...

The Cramér-Rao Lower Bounds (CRLB) are derived for the displacement and strain estimation in directions orthogonal to the ultrasonic beam axis, using a previously-described recorrelation method of axial, lateral and elevational motion estimation. We also compare it to the lateral tracking method that involves the sole use of the axial signal in the transverse direction. Our theoretical results,...

A number of important anatomical features and chemical composition in opposite, normal, and compression wood of Norway spruce (Picea abies) were evaluated to optimally utilize spruce logs containing compression wood. A comparison of axial tracheid and ray cell features in the opposite, normal, and compression wood was provided. Lignin, cellulose, acetone-soluble, and water-soluble extractive co...

The problems of the mechanical state rocks and other brittle materials are studied from different sides in a large number publications, flow which does not weaken with time, is explained by relevance complexity these problems. Quantitative values strength characteristics such can be obtained experimentally or using numerical analytical models. This work aimed at developing an model for analyzin...
