Abstract
Disclosed are a tube pure shear loading device and method. A first mandrel penetrates into a first half tube, and a second mandrel penetrates into a second half tube. The size of the first mandrel matches the size of the first half tube, and the size of the second mandrel matches the size of the second half tube. A first connecting portion of the first mandrel and a second connecting portion of the second mandrel are loaded, and a first protruding portion and a second protruding portion transmit a force to a to-be-tested tube, so that a material of a whole tube in the same plane as a right plane or a left plane of the first half tube and a left plane or a right plane of the second half tube is in a pure shear stress state.
