In this work, we use the rule of mixtures to develop an equivalent material model in which the total strain energy density is split into the isotropic part related to the matrix component and the anisotropic energy contribution related to the fiber effects. For the isotropic energy part, we select the amended non-Gaussian strain energy density model, while the energy fiber effects are added by ...

Deposition processes control the properties of thin films; they can also introduce high residual stresses, which can be relieved by delamination and fracture. Tungsten films with high 1–2 GPa compressive residual stresses were sputter deposited on top of thin (below 100 nm) copper and diamond-like carbon (DLC) films. Highly stressed films store large amounts of strain energy. When the strain en...

Final step of rail manufacturing is cold rolling straightening process and it hassignificant effects on mechanical properties, straightness, flatness and development of residualstresses. Measurement of residual stresses after straightening process is obligated by railmanufacturing standards. In the present investigation, an attempt has been made to evaluateresidual stresses after straightening ...

residual stress measurement has gained interests among researchers for many years due to its great influence on the structural integrity. slitting method is one of the destructive techniques that relies on the introduction of an increasing cut to a part containing residual stresses. similar to all other mechanical strain relief techniques, slitting also suffers from its shortcomings during the ...

We propose a Widom-like scaling ansatz for the critical jamming transition. Our ansatz for the elastic energy shows that the scaling of the energy, compressive strain, shear strain, system size, pressure, shear stress, bulk modulus, and shear modulus are all related to each other via scaling relations, with only three independent scaling exponents. We extract the values of these exponents from ...

sensor networks generally consist of a very great number of sensor nodes which will be spread into a vast environment and aggregate data out of it. the sensor nodes are afflicted with some limitations as follows memory, reception, communication as well as calculation capability, and battery power. the transmission of a great amount of extra data increases data transmission and proportionally in...

biomechanical properties of soft tissue, such as liver, are important in modeling computer aided surgical procedures. experimental evidences show that liver tissue is transversely isotropic. in this article, considering the liver tissue as an incompressible fiber-reinforced composite with one family of fibers, an exponential strain energy function (sef) is proposed. the proposed sef is based on...

In the process of roadway excavation, rock mass around is often subjected to cyclic loads, and mechanical properties strain energy evolution under loads are obviously different from those compression, so it urgent carry out research on loads. This study aims investigate residual in rocks uniaxial loading-unloading experiments (UCLUE). Four types rocks, namely coal, white sandstone, red granite,...
