Abstract:Here, we experimentally and theoretically examined the fastening characteristics and internal axial force of magnetostrictive composite bolts using magnetic flux‐density change. Magnetostrictive composite bolts were fabricated using FeCo wire and epoxy resin by applying magnetic field and preload. The advantage of using a bolt made of magnetostrictive composite materials is that it will have reduced weight and can be applied to prestress. Tightening tests were conducted, with and without external‐bias magnetic… Show more
