A new criterion of coal burst proneness based on the residual elastic energy index
International Journal of Mining Science and Technology, 2021 To evaluate the coal burst proneness more precisely, a new energy criterion namely the residual elastic energy index was proposed. This study begins by performing the single-cyclic loading-unloading uniaxial compression tests with five pre-peak unloading

Ductile crack propagation with the strain-energy density criterion [PDF]
, 1985 The strain energy density criterion is used to characterize subcritical crack growth in a thin aluminum alloy sheet undergoing general yielding. A finite element analysis which incorporates both material and geometrical nonlinear behaviors of the cracked

Strain energy density approach for brittle fracture from nano to macroscale and breakdown of continuum theory [PDF]
, 2021 In contrast to the great success at the macroscale, fracture mechanics theory fails to describe the fracture at a critical size of several nanometers due to the emerging effect of atomic discreteness with decreasing material size.
