Micromechanical modelling of damage induced by delayedettringite formation in concrete [PDF]
MATEC Web of Conferences, 2020 A multi-scale poromechanical model of damage induced by Delayed Ettringite Formation (DEF) as a consequence of progression of micro-cracks at the fine aggregate scale is developed.

A novel weight function for RMS stress intensity factor determination in surface cracks [PDF]
, 2010 This paper discusses the problem of stress intensity factor determination in surface cracks. In particular, the concept of root mean square stress intensity factors (RMS SIF) is discussed for the general class of semi-elliptical surface cracks.

Interstratal dewatering origin for polygonal patterns of sand-filled cracks: a case study from late Proterozoic metasediments of Islay, Scotland [PDF]
, 1998 Sand-filled cracks from the Lower Fine-grained Quartzite of Dalradian (late Proterozoic) age on the Island of Islay, western Scotland, may be divided into two main types, both of which form orthogonal and non-orthogonal closed patterns on bedding ...

Analysis of the cracking mechanisms in pre-cracked sandstone under radial compression by moment tensor analysis of acoustic emissions [PDF]
Archives of Civil Engineering, 2022 Rock masses, especially those with different pre-existing cracks, are prone to instability and failure under tensile loading, resulting in different degrees of engineering disasters.

A fatigue multi-site cracks model using coalescence, short and long crack growth laws, for anodized aluminum alloys [PDF]
, 2010 It has been shown that decrease of the fatigue life of aluminium alloys treated with anodization can be explained by the degradation of surface condition due to pickling.

Source analysis of acoustic emissions during granite strain burst
Geomatics, Natural Hazards & Risk, 2019 The acoustic emission (AE) location technique and fault-plane solution method were used to evaluate the temporal-spatial evolution, released energy variation of micro-cracks, and the difference in b-values for different types of micro-cracks during ...

Crack path and fracture surface modifications in cement composites [PDF]
Fracture and Structural Integrity, 2015 There is a tremendous increase in the use of high strength and high performance self-consolidating cementitious composites due to their superior workability and mechanical strengths. Cement composites are quasi-brittle in nature and possess extremely low
