On the Expected Relationships among Apparent Stress, Static Stress Drop, Effective Shear Fracture Energy, and Efficiency Available to Purchase
Publisher: Seismological Society of America
Published: 01 June 2003
Bulletin of the Seismological Society of America (2003) 93 (3): 1381–1389.
...N. M. Beeler; T.-F. Wong; S. H. Hickman Abstract We consider expected relationships between apparent stress τ a and static stress drop Δ τ s using a standard energy balance and find τ a = Δ τ s (0.5 – ξ ), where ξ is stress overshoot. A simple implementation of this balance is to assume overshoot...
