Initial stress and strain

Webb28 maj 2024 · It was shown that the initial stress and strain state, which can be tailored by an Au interlayer in FePt/Au/FePt trilayers, affect the ordering process and, thus, the magnetic properties. More specific, large compressive strain in the as-deposited FePt layers promote the L1 0 -FePt phase formation.

Webb29 aug. 2024 · When applying a load to a part, initially the relationship between stress and strain is linear. While the relationship remains linear, it is considered the elastic region of the material. In the elastic region of the material, when the stress is removed, the part returns to its original shape.

Webb20 juni 2010 · Unfortunately, it is not really physically accurate to have a constant initial stress. What happens is that the initial stress is not consistent with the boundary conditions and the interface between the softer and the stiffer material. This causes the solution to be somewhat strange. WebbWe determine the corresponding constitutive relations and develop examples of nonlinear strain energies that depend explicitly on the initial stress and direction of texture anisotropy. As an application, we then employ these models to analyse the stress distribution of an inflated initially stressed cylinder with texture anisotropy and the …
