Failure Identification Using Model-Implemented Fault Injection with Domain Knowledge-Guided Reinforcement Learning [PDF]

open access: yesSensors, 2023
The safety assessment of cyber-physical systems (CPSs) requires tremendous effort, as the complexity of cyber-physical systems is increasing. A well-known approach for the safety assessment of CPSs is fault injection (FI).

Fault Reactivation by Fluid Injection: Controls From Stress State and Injection Rate

open access: yesGeophysical Research Letters, 2018
We studied the influence of stress state and fluid injection rate on the reactivation of faults. We conducted experiments on a saw cut Westerly granite sample under triaxial stress conditions.

Modelling of fault reactivation mechanisms and associated induced seismicity in rocks with different elastic materials

open access: yesPetroleum Research, 2022
The mechanical failure of fault plane during fluid injection can be conveniently approached by numerical methods, and the results can be applied in fault slip analysis to determine the corresponding magnitude of induced seismicity. During hydrofracturing,
