The deformation of polycrystalline beryllium to strains of 60.8 pct in uniaxial tension and compression was studied by neutron diffraction and modeled using an elasto-plastic self-consistent (EPSC) model. The beryllium response is asymmetric with respect to tension and compression in both the macroscopic behavior, as displayed in the stress/strain curve, and the microscopic lattice response. Th...

Compressibility of a soil mass is its susceptibility to decrease in volume under pressure and is indicated by soil characteristics like coefficient of compressibility, compression index and coefficient of consolidation. However, the determination of soil compressibility characteristics in the labs is a cumbersome and time consuming process, especially in the case of fine grained soils. In the p...

An electrochemical etching approach was developed to fabricate self-similar nanoand microscale pyramid structures on singlecrystal gold (100) surfaces. Using their unique self-similar characteristics, pyramids of (114) facets were compressed to study the length scale effects in the contact pressure and plastic deformation. At first, many pyramids were compressed simultaneously with a flat mica ...

Coupled plastic flow and strain-induced phase transformations (PTs) under high pressure and large plastic shear in a micron scale sample under loading, unloading, and reloading in a rotational diamond anvil cell (RDAC) are studied in detail, utilizing finite element approach. A plastic strain-controlled, pressuredependent kinetic equation, which describes strain-induced PTs, is used. The effect...

Motivated by a model that qualitatively captured the response of vertically aligned carbon nanotube (VACNT) pillars in uniaxial compression, we consider the uniaxial tensile response of a class of compressible elastic-viscoplastic solids. In Hutchens et al. [“Analysis of Uniaxial Compression of Vertically Aligned Carbon Nanotubes,” J. Mech. Phys. Solids, 59, pp. 2227–2237 (2011), Erratum 60, 17...

This article deals with the nonlinear behavior of trabecular bone tissue under uniaxial compression. The model this is a stress-strain curve an ascending branch, peak point, and descending branch. known predicts at pre-peak partially post-peak stage deformation. does not take into account transition plastic deformation appearance residual deformations, which (depending on scale) may be physiolo...

Laminated fibre-reinforced polymer (FRP) tubes are increasingly used as compression members in large-span spatial structures due to their high bearing capacity, corrosion resistance, and superior stability compared high-strength steel pipes. In this study, axial tests were conducted on slender BFRP evaluate characteristics members. The results indicated that exhibited three distinct failure mod...
