The recent rapid developments in electronic computers have frequently encouraged parallel developments in methods of analysis of engineering problems. In the field of structural analysis, for instance, great strides have taken place in the use of methods variously termed “matrix methods” or “finite element methods”, and the methods have found wide application in dealing with highly complex structures. As the first step of their application to analysis of ship structures, computing program for stress analysis of two-dimensional structural members is developed with some numerical examples.
