Damage Identification Research of Cantilever Truss Based on the Principle of Strain Mode
This paper presents a method converting the modal distance of the node into elemental strain based on the special characteristic of two-force element. The strain change before and after damage is applied to the damage identification. The change rule of the relative strain for the same location of the truss occur the various damage extent and the various location of the truss occur the same damage extent, respectively, is obtained according to the strain modal simulation using APDL language. The simulation results show that the strain modal change ratio is sensitive to the cantilever truss damage detection. The damage location and damage extent will be identified. It is an effective nodestructive test way to identify the cantilever truss structural damage.
