In addition to the previous strains there is another strain known as the hoop strain, ε t, and a corresponding hoop stress, σ t. The hoop strain results from the change in length of a fiber of material around the circumference of the solid.
15 lis 2013 · In the present work, by hoop strain measurements during cooling and excitation, the behaviors of thermal and electromagnetic deformation in multicomponent superconducting solenoids were evaluated.
tension, the deformation process of the hoop specimen is mechanically modeled, and the plastic strain hardening parameters of the material are obtained by the inverse fitting method. The re-sults obtained by this method can whether it accurately reflects the hoop hardening performance of the tube needs further research.
15 lip 2024 · In this study, we propose a novel testing technique, namely the ring hoop plane strain Test (RHPST), as a supplementary test for characterizing materials experiencing distinct strain paths compared to standard uniaxial tensile tests.
1 wrz 2014 · We found that the contact pressure and the contact-induced radial stress cause limited deviations from uniaxial tension, comparable to the case of a tube under axial load and internal pressure which is often used for assessing the material properties in the hoop direction.
Hoop stress occurs in both directions and is similar to the way a hoop or a ring is stressed when it is stretched or compressed. In this article, the focus is on the derivation of the formula for hoop stress for both thin-walled and thick-walled pressure vessels.
10 wrz 2020 · The hoop tensile strength predicted agreed with experimental observations very well, validating the finite-element modeling. The damage progression was monitored during different loading stages, and the sequence of experienced failure modes was investigated.
