In this paper, the nonlinear anisotropic hyperelastic model recently proposed by Houlsby et
al.(2019) is critically analysed and validated against experimental data. The model, here …

Poisson's ratios and small-strain stiffnesses of three kinds of granular materials—fine,
medium coarse, and coarse sands—were evaluated in the laboratory. Both axial and radial …

A triaxial test apparatus combined with two independent wave measurement methods, ie
Trigger Accelerometer and Bender Element, was employed. A series of tests were …

Piezoelectric effect is defined as the relation between mechanical distortion and an electrical
voltage in solids. This effect was discovered in 1880 by Jacques and Pierre Curie brothers …

Piezo-ceramic elements have been extensively used for measurement of elastic wave
velocity in laboratory soil specimens. This paper presents a study of the flat shaped disk type …

A new receiving transducer derived by piezoceramic bimorfh for the elastic wave
measurement method suited on triaxial apparatus is developed. The bimorph receiver was …
