WebAn object or medium under stress becomes deformed. The quantity that describes this deformation is called strain. Strain is given as a fractional change in either length (under tensile stress) or volume (under bulk stress) or geometry (under shear stress). Therefore, strain is a dimensionless number. Web3 Jun 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.
