Fracture Energy and Aftershocks [PDF]
Geophysical Journal International, 1976 Summary The b-value of the frequency-magnitude relationship for aftershocks increases with the fracture energy yo of the mainshock according to the empirical relationship, b = 0.06 log yo + 0.48 I', = 0.53 where rc is the correlation coefficient. Thus for large yo, a fair proportion of the aftershocks will have small magnitudes while the converse is ...

The Fracture Energy of Earthquakes [PDF]
Geophysical Journal International, 1975 Summary The arrest of a semi-infinite longitudinal shear crack is caused by either (1) the finiteness of available strain energy, or (2) an increase in fracture energy along the trajectory of the running crack. In the former case the following relationship may be used to evaluate the fracture energy: yo = RAa2/2ptn where yo is the fracture energy per ...

A Direct Tensile Strength Testing Method for Concrete from Existing Structures
CivilEng, 2023 Tensile strength is a crucial property for the function, safety and durability of all concrete structures. The general procedure to assess the tensile properties of concrete from existing structures is to perform indirect tests and predict the tensile ...

The Fracture Energy and Some Mechanical Properties of a Polyurethane Elastomer [PDF]
, 1971 The energy required to form a unit of new surface in the fracture of a polyurethane elastomer is determined. The rate sensitivity of the material has been reduced by swelling it in toluene.

Parametric Investigation on the Effectiveness of FRM-Retrofitting in Masonry Buttressed Arches
Buildings, 2021 Buttressed arches represent some of the most vulnerable elements in historical masonry buildings under seismic actions. Given their structural, architectural and often artistic importance, it is paramount to investigate effective retrofitting measures ...

Downscaling of fracture energy during brittle creep experiments [PDF]
, 2011 We present mode 1 brittle creep fracture experiments along fracture surfaces that contain strength heterogeneities. Our observations provide a link between smooth macroscopic time-dependent failure and intermittent microscopic stress-dependent processes.

High-Energy Fracture of the Fabella
Radiology Case Reports, 2010 Fractures of the fabella are rare, with only nine cases reported in the literature. However, they can cause severe posterolateral knee pain. Other complications include osteoarthritis and, very rarely, peroneal nerve compression. All the prior cases have been transverse fractures.
