Abstract
This paper describes briefly techniques for the rapid preparation of optically flat metal plates to an accuracy of approximately two interference bands over an 8-in. span. The construction and use of two large Fizeau interferometers for observing defections resulting from flexure is described The technique was developed 'as an experimental means of circumventing the very great theoretical complexity of analysing various forms of flexed multiply-connected plate occurring in engineering construction. It is illustrated qualitatively from studies of perforated circular plates subjected to lateral loading, of annular and triangular plates subjected to concentrated loads and of perforated bars subjected to pure bending Quantitative studies based on the method are to be described in subsequent papersKeywords
