This understanding of the lateral strain-to-axial strain relationship is of particular importance for prestressed CFFTs due to the influence of the additional lateral prestrain. Initially a database that consists of 23 aramid FRP- (AFRP) confined HSC cylindrical specimens with lateral prestress of ...

The crack band model, which is easier to implement and is used in commercial codes (e.g., DIANA, SBETA) [49], is, for localized cracking or fracture, nearly equivalent to the cohesive crack model ([BP], [97]), provided that the effective (average) transverse strain in the crack band...
Based on this theory, the stress field at an arbitrary point is a function of the strain field at all the points within the body. One of the most significant nano-scaled mechanical elements is represented by nanobeams, as largely applied in many nanotechnology applications, e.g. nano-...

Although strain gauge load cells are the most common, hydraulic (or hydrostatic), piezoelectric load cells, and vibrating wire load cells can also generally be used. In one embodiment, the force sensor 310 comprises a dynamometer. A dynamometer can measure the axial force (Fz), in plane ...
The angle of deformation γ, or shear strain as defined by ASTM E519-02 (ASTM2002), is the sum of the absolute vertical and horizontal strains, εvand εh, respectively (Eq.2). The strain values were obtained from full-field DIC measurements using a virtual gauge of 900 mm length as...
A porous Al2O3 cylinder was placed on its uncut tibial side and a material testing machine (BXC-EZ001.A50000, ZwickRoell GmbH & Co. KG, Germany) equipped with a stainless-steel punch applied the respective strain level/axial deformation, which was registered using a laser (OptoNCDT 2200, ...
Moreover, a theoretical stress–strain model for circular cross-sections made of concrete confined by GFRP hoops was proposed by Afifi et al. [34] as a modification of the well-known model proposed by Mander et al. [35]. The proposed model showed a reduced confinement capability of GFRP ...
