The article presents the research results on geomechanical processes related to the change in the stress-strain state in the rock mass during large-scale mining operations in highly stressed rock massifs. A geomechanical model has been created that allows considering the sequential development of a complex of adjacent deposits at the Khibiny rock massif. Based on the modeling results, the optimal order and direction of development of mining operations under rockburst hazardous conditions are determined. At that, t...

Fatigue damage is determined from time signals of loading, usually in the form of stress or strain. However, there are many design scenarios when the loading, or fatigue damage process, cannot easily be defined using time signals. In these cases the design/operation engineer usually has to use a test based approach to evaluate the fatigue life of the structure or the component. Alternatively, a frequency based fatigue calculation can be used where the loading and response are represented using Power Spectral Densi...
