| Abstract: | This paper describes a finite element method for solving contact problems
of elastic bodies with initial gaps and friction between them.The mtheod has
been examined by applying it to the Hertz problem and to shringkage fit prob-
lems.Its results quite agrees with the corresponding exact solution.By use of
the finite method the authors have completed the struoture and strength design
of blade root fastenings and large-sized shrunk-on discs of steam turbines,some
of which have already come into use in engineering. |
