Abstract: A transparent constraint apparatus for the normal deformation of a planar model, including rigid transparent retainer plates, a planar model, and magnetic force components. The magnetic force components are provided at edge positions of the rigid transparent retainer plates; the normal direction of the planar model is parallel to the normal direction of the two rigid transparent retainer plates, and said two retainer plates are symmetrically arranged relative to the plane of symmetry of the planar model; the magnetic force components are symmetrically arranged relative to the plane of symmetry of the planar model, mutually symmetrical magnetic force components producing mutually attractive magnetic force. The transparent constraint apparatus solves the problem of constraining the normal deformation of a planar model under planar-strain conditions during testing.

Abstract: A fluid pressure loading device applied to an industrial computed tomography scanning test system includes a body, a sample accommodating chamber and at least one fluid medium chamber being provided in the body. Each of the at least one fluid medium chamber is provided therein with a piston, the corresponding fluid medium chamber is separated into two chambers by the piston, one of the two chambers is in communication with an external hydraulic medium via oil lines provided in the body, the other of the two chambers is in communication with the sample accommodating chamber, and one end, facing towards the sample accommodating chamber, of the piston is extendable into the sample accommodating chamber. With the loading device, real-time loading of a test sample can be realized, thus improving a simulation accuracy of the system, and multi-directional loading of the sample can be realized.
