Two techniques are necessary when using physical models to assist with structural design – being able to measure the deformation of the small model to sufficient accuracy, and being able to use these measurements to predict deflections and stresses in a full‐size structure, especially when structural phenomena such as buckling cannot be scaled up linearly. William Froude developed an approach using non‐dimensional numbers to deal with questions of scale in fluid mechanics in the 1870s. This approach was made more versatile by Edgar Buckingham (his pi‐theorem) in the 1910s and was adopted in civil and building engineering from the 1930s.
Mechanical strain gauges were used in the 19th century but these were too large for use on models. The breakthrough came with the Huggenberger strain gauge developed in the 1920s which was widely used until the 1960s. Acoustical strain gauges were used in the 1930s, but were not suitable for miniaturisation. Electrical resistance strain gauges were first developed in the 1930s and became the instrument of choice from the late 1940s when foil gauges were first developed.
