In a few simple steps, you will learn the stress vs. strain relationship for any material that remains elastic. We will also teach you how to calculate strain and how to apply the stress equation. 🔎 This calculator deals with axial stress. If you're studying transverse shear, you should...
Understand what stress and strain are and learn the equations for stress or strain. Know the difference between tensile and compressive stress.

The thin curves of Figure 18 were plotted assuming that damage growth vs. plastic strain was given by D=(ɛp/ɛpR)2. The integration of Equation (97) is made step-by-step by a simple analytical rule. Obviously, Equation (93) remains valid but, in the case of isotropic damage, ...

However, we note that the scaling that was applied in this work does not allow the resolution of short-lived stress drops since this would also require the consideration of the inertial terms (equation 4; METHODS section). We therefore limit the applicability of our results to the long-term ...

The strain-time history at different locations on the rod's surface was recorded by a 200 MHz transient recorder. The calculated yield stresses ranged at a level up to three times the static value, at a rate of 3000 1/s. In the plastic regime, the shape of the stress-strain curve ...
Moreover, since the residual stresses are calculated from the strain in the lattice, the measurements are not significantly affected by the material properties, e.g., hardness and extent of cold work [11]. The objective of the study was to investigate the effect of LPBF process parameters ...
This differential equation (Eq. (6)) can be solved analytically to give the accommodation stress as a function of time t (assuming that the initial σθ = 0), namely: $${\sigma }_{\theta } = k \left(\frac{{P}_{0}}{\frac{1}{\mu }+k}-\frac{{P}_{0}}{\frac{1}{\...
