In this paper we present results concerning the magnetostrictive delay
line (MDL) response for positive magnetostrictive wires as well as th
e magneto-inductive (MI) response for negative magnetostrictive wires,
on the applied torsion and tensile stress. The obtained results show
a non-monotonic dependence of the MDL response and a parabolic magneto
-inductive response on applied torsion. The tensile stress dependence
in MDLs could be fitted by a linear curve for as-cast wires, and by an
exponential curve for annealed wires while the MI response could be f
itted by a linear curve. Load cells and torque sensors may be realised
by using this technique. (C) 1997 Elsevier Science S.A.
