Energy Analysis and Experiment of Breaking Cobalt-Rich Crust
Abstract The uniaxial compressive breaking process of energy of deep-sea Cobalt-Rich Crust was selected as researching content, and the calculation of energy conversion of breaking Cobalt-Rich Crust under loading and unloading conditions was described in detail, and also the specimens of Cobalt-Rich Crust were tested in rock mechanical testing system under the specified stressing paths. From experimental data, the elastic energy, the dissipated energy and the total inputting energy of unloading points were analyzed systematically. The conclusions are as follows: (1) the specimens of Cobalt-Rich Crust are anisotropic rock, and different testing specimens need to load different axial forces to break, and the maximum of axial force is 8KN, and the minimum is 5KN; (2) when increasing the axial force, the elastic energy, the dissipated energy and the total inputting energy of the unloading points increased nonlienearly; (3) Cobalt-Rich Crust is not the same with other ordinary elastic rock, the elastic energy is lower than the corresponding dissipated energy, and with the increasing of the axial force, the difference between two values becomes more and more.
