| Abstract: | Based on the slightly bend differential equation of a compression bar,a precise transfer matrix format for the elastic bending analysis of the compressive-bending bar under different loads is derived through the precise transfer matrix method.Internal forces of the compressive-bending bar with different boundary constraints are calculated by the mothod.Examples show that the method is right and effective. |
