Creep tests up to 106 seconds in tension and compression were conducted on polymethyl methacrylate (PMMA), polyvinyl chloride (PVC), and polypropylene (PP). Measurements of longitudinal and lateral strain provi
The lateral strain to linear strain ratio in the loading direction is defined as Poisson's ratio. Poisson's ratios range from 0.15 to 0.25. A lower Poisson's ratio indicates brittleness in a greater strength concrete. HPC is currently commonly used in bridges and other constructions. Current ...
When a tensile stress or compressive stress is applied to a cylinder or rod, there is simultaneous axial and lateral strain within the elastic range. The ratio of the lateral to the axial strain is called Poisson's ratio. It has no unit, as it is the ratio of two strains. Most rigid ...
In essence, the effect of the free surface is to disrupt the primary upflow mechanism and also to induce lateral spreading of the top portions of the Kármán vortices. View article Journal 2005, Journal of Sound and VibrationR.D. Gabbai, H. Benaroya Related terms: Energy Engineering ...
In this work, the evolution of the viscoelastic Poisson's ratio of the commercial LY5052 epoxy resin is studied in relaxation test subjecting the specimen to constant axial strain. Specimens at several cure states are studied and Poisson's ratio, defined as the lateral and axial strain ratio,...
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...
s functions which account for changes ofpat constant stress ratio have at least one conceptual shortcoming. They were designed to simulate consolidation and one cycle of unloading and reloading only. This first cycle induces a certain amount of permanent deformation because the stress–strain loop is...
Consequently, we demonstrate stretchable OLEDs with both the high initial active-area ratio of 85% and the system strain of up to 40%, which would require a lateral inter- connector strain of up to 512% if it were attained with conventional 2D rigid- island approaches. These OLEDs are ...
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 ...
The presence of both lateral and axial deformations on a planar substrate is commonly referred to as 2.5D-TFM while early 2D-TFM works21,31 were only able to capture two-dimensional (2D) lateral displacements of the fidu- cial markers. In case (ii), referred to as 3D-TFM, the ...
