RVE can show the real stress and strain of a material and offers a good understanding of its elastic properties.
In the present study, the contraction stress was analyzed by photoelastic analysis, in which the internal stresses of a photoelastic material are transformed by visible light to determine the location and magnitude of the stress.
A shear stress is defined as the component of stress coplanar with a material cross section; it arises from the force vector component parallel to the cross section.
In the lubricated simulations, the lower shear stress and the absence of a material transfer are attributed to hexadecane monolayers that are partially tethered to the a-C H surfa-C Hnd surfacecandly reduce adhesignificantlyanical mixing between the sliding pareduce.
The method involves using a laser beam to locally heat and reduce the flow stress of the material ahead of an advancing cutting tool, making the metal shearing process easier.
Second, in addition to achieving low modulus, a large strain recovery of the material should be attained, which can be done either by increasing the yield stress of the material by creating a favorable microstructure and phase composition or by the implementation of a reversible martensitic transformation [12 15].
In this paper, the distributions of the temperature, moisture, displacement and stress of a functionally graded piezoelectric material (FGPM) circular disk rotating around its axis at a constant angular velocity under a coupled hygrothermal field are presented by a numerical method.
The definition of the shear stress amplitude on a material plane as well as the evaluation of the amplitude of the second invariant of the stress deviator can be led back to an optimization problem which can be quickly solved with already existing routines.
Peening, which is a surface treatment used to introduce compressive residual stress to enhance the mechanical properties of a material, such as its resistance to stress corrosion cracking and its fatigue strength, may, therefore, suppress the embrittlement caused by hydrogen.
