Earthquake breakdown energy scaling despite constant fracture energy. [PDF]
Nat Commun, 2022 AbstractIn the quest to determine fault weakening processes that govern earthquake mechanics, it is common to infer the earthquake breakdown energy from seismological measurements. Breakdown energy is observed to scale with slip, which is often attributed to enhanced fault weakening with continued slip or at high slip rates, possibly caused by flash ...

Application of fracture energy for the assessment of frost degradation of high-strength concretes
Budownictwo i Architektura, 2021 Knowledge of fracture mechanics parameters can help for a more accurate assessment of frost degradation of high-strength concrete. High strength concretes, despite the tight structure, are characterized by increased brittleness.

Low energy fractures of the acetabulum [PDF]
The Annals of The Royal College of Surgeons of England, 2014 Introduction Acetabular fractures due to high energy injuries are common and well documented; those secondary to low energy mechanisms are less well described. We undertook a retrospective study of the acetabular fracture referrals to our unit to evaluate the proportion of injuries resulting from a low energy mechanism.

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 ...

Experimental investigation on mode II fracture performance of old-new concrete [PDF]
Archives of Civil Engineering, 2022 The old-new concrete interface is the weakest part in the composite structure, and there are a large number of microcracks on the interface. In order to study the mode II fracture performance of the bonding surface of old-new concrete, the effect of ...

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 ...

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 ...
