The Research of the Bending of Triangle Plate in One Boundary With Mixed Variable Method

摘要

In many engineering, the moment will have the influence of the bending of the triangular plate. The bending problem of under a concentrated bending moment is discussed. The principle of mixed action with variables [1] is applied to calculate equation, which are given two border and trilateral fixation without assuming the complicated function of placement. Then the corresponding equations can be attained basing on all kinds of boundary conditions straight girder and elastic thin triangular plate. So, fussy processes are overcome and this method is fitter for the problem to solve difficulty by the others method. This method is simple and clear, and by it the complicated solutions for the problems of cantilever triangular plate are simplified. The corresponding chart and the result are given. The result can be a reference for engineering and give an efficacious, simple, convenient method to design for bending plate of structures.
