WebJun 3, 2024 · The formula for calculating material stress: σ=F/A, where. F is force (N) A is area (m 2) σ is stress (N/m 2 or Pa) For example, a force of 1 N applied on a cross-sectional area of 1 m 2, will be calculated as a stress of 1 N/m 2 or 1 Pa. The unit can be displayed as N/m2 or Pa, both of which represent pressure. WebSep 12, 2024 · In the linear limit of low stress values, the general relation between stress and strain is stress = (elastic modulus) × strain. As we can see from dimensional analysis of this relation, the elastic modulus has the same physical unit … WebThe graph of these quantities with the stress σ along the y-axis and the strain ε along the x-axis is called the stress-strain diagram.
