| Abstract Scope |
The idea of the sensory magnetic particles for crack detection arises from their phase transforming ability causing their magnetism to alter accompanied with martensitic transformation. Micron-sized ferromagnetic shape memory alloy (FSMA) particles are to be embedded in structural materials to detect any stress-induced cracks within the materials. In this work, we investigate 1) material selection and material processing for an adequate type of magnetic particles, 2) proper embedding of the particles in the structural materials, 3) how to confirm the sensing ability through the whole "composite" material we create. This study shows promising results on utilizing FSMA particles for structural health monitoring. |
