| Abstract: | Based on the simulation of external installation and embedding of shape memory alloy in the bending beam structure,field tests and the finite element software ANSYS were combined to establish the calculation model and research carrying capacity of the beam before and after alloy installation and the recovery of cracks. The results show that external installation and embedding of shape memory alloy effectively reduce the deformation of the beam under load and facilitate the self-repairing of the structure. Thus, the alloy installation method improves bearing capacity and mechanical performance, and strengthens structural integrity and rigidity. |
