Abstract The whole process of strain energy conversion of shale in absorbing the axial strain energy ，storing and releasing the elastic strain energy ，dissipating the energy for plastic deformation and cracks propagation，expending strain energy for circumferential deformation was studied based on the energy theory and the shale tests under traixial cyclic loading. The variation of shale energy was revealed，and the criteria for strength failure of shale was established based on the energy catastrophe. The variation of behavior of shale specimen under the different confining pressures in the test of traixial cyclic loading was found to be similar and dominated by the energy accumulation before the peak stress，then the energy dissipation and releasing were predominant in the failure stage after the peak stress，the energy accumulation restarted after the shale specimen reached its residual strength，but its efficiency and capability was inferior to those before peak stress. In the failure stage，the elastic strain energy was released in large quantities along the main fracture，the dissipating energy was consumed largely when the fractured rock mass frictionally slid along the main fracture，and the expending strain energy grew substantially with the radial strain. Comparing with that before the peak stress，the magnitude of the elastic strain energy and the dissipating energy in the stage of residual strength decreased substantially but have maintained stable while the expending strain energy increased a lot. The confining pressure did not affect much the energy ratio in the stage before the peak stress，but enhanced the efficiency and capbility of energy accumulation in the stage of residual strength. In the stage before the peak stress，the consumption ratio of elastic energy of shale and red sandstone decreased slowly with the axial strain，its changing rate went smoothly. In the failure stage，the inflection point of the elastic energy consumption ratio appears with a significant increasing in magnitude and growth rate.
