Title:
BIAXIAL FOUR-DIRECTION DYNAMIC AND STATIC COMBINED ELECTROMAGNETIC LOADING HOPKINSON PLATE IMPACT LOADING DEVICE
Document Type and Number:
WIPO Patent Application WO/2021/012459
Kind Code:
A1
Abstract:
Provided is a biaxial four-direction dynamic and static combined electromagnetic loading Hopkinson plate impact loading device, which comprises a loading frame system, a rod system, an electromagnetic pulse transmitting system, a biaxial four-direction confining pressure servo control loading system, and a data monitoring and collecting system. The device is used to systematically carry out a two-dimensional plane stress wave dynamic impact test of large-size rock materials with a width of 200mm-500mm in the biaxial four-direction pre-stressed state, so that a dynamic mechanical response of a large-size rock mass structure under different initial confining pressure states and strain rate conditions is studied, a breaking mechanism of the rock mass structure under the action of dynamic and static combination is analyzed, and a dynamic damage and fracture theory of the rock mass materials is establish for guidance and application in the rock mass engineering practice.
