Bubbling experiment device for mechanical-electric-magnetic coupling behavior of electromagnetic intelligent material and test method

The invention discloses a bubbling experiment device for the mechanical-electric-magnetic coupling behavior of an electromagnetic intelligent material and a test method. In the invention, the tested film material is subjected to elastic deformation, plastic deformation, interface cracking and even self fracture by a bubbling method under the effect of full coupling of the mechanical-electric-magnetic fields, and the device realizes real-time testing on the mechanical, electric and magnetic response of the tested material in the process, thereby being favorable for obtaining the information of the functional film material in multiple aspects and for understanding the internal mechanism more clearly and thoroughly; in the existing oil-pressure bubbling loading device, a closed-loop control mode is adopted to control the oil pressure loading for the first time, and multiple oil pressure loading modes are realized so as to widen the representation functions of the bubbling test device; by adopting the projection speckle and digital image related technology, the non-contact three-dimensional deformation test is realized on the film sample, and the displacement measurement accuracy is improved to 20nm; and the device and method are favorable for researching the mechanical, electric and magnetic comprehensive performance of the novel functional film material.
