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

Strain energy density evaluation with free coarse mesh model [PDF]
Material Design & Processing Communications, 2019 This work investigates the error in estimating the strain energy density value through a free coarse mesh model in a finite element analysis. Several numerical simulations were carried out to acquire this value both according to the conventional methodology of the strain energy density method and according to the procedure shown in the present work ...
