WebOct 29, 2024 · 3. Plastic deformation occurs when the applied stress causes atomic planes to slide with respect to one another. You can see then why shear is a more "stressful" state than traction: it is more likely to cause sliding. For the same reason, a hydrostatic pressure (usually) does not contribute to the yield stress and only the deviatoric does. WebUnlike nontensor approaches, the dimensionality in the tensor approach can be eliminated. Thus, EDS is defined as the ratio of the Euclidean distance (d S, S ′) between the measured and predicted stress tensors to the Euclidean distance (d S, O) between the measured stress tensor and origin (in a two-dimensional (2D) space as shown in Fig. 2): (9) EDS S, S ′ = d S, … first article tests https://unique3dcrystal.com
