| Abstract: | In this paper,the general equation is
concluded for analysis of stability of uniform section bar bearing axial pressure.Its
solution is brief and suitable to different kinds of constraints at the ends of bars.This
method of transfer matrix can easily evaluate the critical load of bars of non-uniform
section,such as bars with elastic bears,without solving complicated differential
equations. |
