  An unexpected failure of a concrete gravity dam may cause unimaginable human
suffering and massive economic losses. An earthquake is the main factor
contributing to the concrete gravity dam's failure. In recent years, there has
been a rise in efforts globally to make dams safe under dynamic loading.
Numerical modeling of dams under earthquake loading yields substantial insights
into dams' fracture and damage progression. In the present work, a
particle-based computational framework is developed to investigate the failure
of the Koyna dam, a concrete gravity dam in India exposed to dynamic loading.
The dam-foundation system is considered here. The numerically obtained crack
results in the concrete dam are compared with the available experimental
results. The findings are consistent with one another.
