Therefore, the d-electron count dependence of the sign of Poisson's ratio as shown in Fig. 2a does not change with respect to the amount of the applied strain within the linear elastic range and the loading direction inside the plane. Stiffness. To compare the stiffness (Young's modulus) ...
That allows to measure axial deformation based on the motor steps. However, the displacements determined this way are distorted by mechanical backlash of the drive system whenever the loading direction changes. To resolve this, a linear variable displacement transducer (LVDT) was added to the GDS ...
The correlation between the longitudinal and lateral deformations of materials is characterized by Poisson’s ratio (μ), defined as the negative ratio of lateral contraction strain (εx) to the longitudinal extension strain (εy) of a material (or structure). The Poisson’s ratio of iso...
Through the statistical analysis of relative frequency, the drift ratio limits of PVA-FRCs under different performance levels with more than 85% safety assurance rate were obtained, which were 1/300, 1/150, 1/80, 1/55 and 1/40, respectively. The performance level, damage state, lateral ...
Strain gauges were positioned adjacent to the regions of contra-curvature on each of the leaf springs in the supporting device to measure the lateral displacement. Load cells placed atop the test cylinder were used to continuously record the fluid forces in the crossflow and inline directions. The...

We are applying uni-axial strain, i.e. alongside one lattice vector, and apply the barostat only in the lateral directions. This will allow us to account for Poisson contractions. Setting up the strain rate¶ The publication Ref. 1 put a linear strain of 20% over the course of 1 ns...
