Estimating the term…
A segmented tube formed of a magnesium-based alloy and wrapped or jacketed with a reinforcement to apply a restraining force on the external surface of the tube for resisting fragmentation of the tube by the compressive force applied to the end of the tube serves as a structural member for receiving a compressive stress applied to an end of the tube and acting along the axis of the tube toward the opposing end of the tube. The magnesium alloy tube is comparatively light, and the segmented and wrapped or jacketed tube has an increased capacity to absorb compressive forces. The tubes are useful as components of automotive vehicles.
A tube formed of a magnesium-based alloy and having a length and longitudinal axis, an internal tube surface and a complementary external tube surface spaced from the internal surface to define a tube wall, and opposing end surfaces spaced along the longitudinal axis of the tube;
A method of making an article having a structural member to absorb a compressive force, comprising providing a hollow structural member formed from a magnesium-based alloy having a length and longitudinal axis, an internal surface and a complementary external surface spaced from the internal surface to define a structural member wall, and opposing end surfaces spaced along the longitudinal axis of the structural member, wherein the structural member is divided into segments along the longitudinal axis,
