Energy storage burst

What is the Energy Storage Index for rock bursting proneness?

A peak-strength strain energy storage index for rock bursting proneness of rock materials Numerical modeling of time-dependent spalling of rock pillars Energy-Absorbing capacity of reinforced shotcrete, with reference to the containment of rockburst damage

What is the energy criterion for coal burst proneness?

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 stress levels to explore the energy storage characteristics of coal.

Is strain energy storage index a rockburst criterion?

New criterion for the spalling failure of deep rock engineering based on energy release Rockburst proneness criteria for rock materials: review and new insights Theoretical verification of the rationality of strain energy storage index as rockburst criterion based on linear energy storage law

What happens during a coal burst?

During coal burst, a portion of the stored elastic strain energy is dissipated through the destruction of coal, with the remainder being released as kinetic energy during the ejection of coal fragments. A greater amount of residual elastic strain energy will produce a more violent coal burst.

What is coal burst proneness?

Based on the linear energy storage law, CEF was proposed to estimate the burst proneness of coal, which is nominally equivalent to the residual elastic strain energy that is released after coal failure. The occurrence of coal burst is essentially a release of the elastic strain energy stored in the coal, leading to the ejection of coal fragments.

Is a flywheel energy storage system a burst containment?

The housing of a flywheel energy storage system (FESS) also serves as a burst containment in the case of rotor failure of vehicle crash. In this chapter, the requirements for this safety-critical component are discussed, followed by an analysis of historical and contemporary burst containment designs.
