Shikazo Iguchi

Shikazo Iguchi studied at the Imperial University in Tokyo from 1912 to 1915. Following that, he was employed as an engineer in the River Training Works Department of the Japanese Interior Ministry. In 1930 he was appointed professor of hydraulic engineering at the Imperial Hokkaido University in Sapporo, and from 1930 to 1932 spent time studying in Germany. After his return to Japan he gained his doctorate at the Imperial University in Tokyo with a dissertation on the bending theory of orthotropic plates (1932). From 1949 until his death he was rector of the Muroran State Technical University. Iguchi contributed to the further development of plate theory in the invention phase of theory of structures. For instance, with the help of Robert Kirchhoff 's (1824–87) plate theory he provided a complete mathematical analysis of Chladni's figures (1797) [Iguchi, 1953].

Main contributions to structural analysis:

A solution for the calculation of a flexible rectangular plate [1933]; A general solution for the buckling of octagonal plates [1936]; The vibrations due to bending stress in rectangular plates encastré on four sides [1937]; The buckling of a rectangular plate due to shear forces [1938]; The natural oscillations and acoustic patterns of simply supported rectangular plates [1953]
