Characterization of transverse anisotropy in Poisson's ratio using three-point radial deformation measurements [PDF]
E3S Web of Conferences, 2019 Poisson's ratio (v) of rock specimens can be experimentally determined from radial deformation measurements in an unconfined compression test. This is commonly achieved by mounting a compressometer with diametric or perimetric measurement capability ...

Design and manufacturing optimization of epoxy-based adhesive specimens for multiaxial tests
Materials & Design, 2021 Specimen design and manufacturing quality are decisive factors in the experimental determination of material properties, because they can only be reliably determined if all undesired influences have been minimized or are precisely known.
