Webb6 feb. 2024 · Strain is a measure of the change in shape or size of an object relative to its original shape or size. For example, the change in length of a spring, Δ L relative to the original length of the spring, L describes the strain of the spring, ϵ = Δ L / L. Both Δ L and L must be measured in the same units (e.g., cm or mm). Webb10 apr. 2024 · Assuming a plane strain condition and superimposing the in-plane plane strain problem, elastic uni-axial stress problem and anti-plane shear problem, a 3D analytical solution is obtained.
