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.

Cracks Cleave Crystals

, 2003
The problem of finding what direction cracks should move is not completely solved. A commonly accepted way to predict crack directions is by computing the density of elastic potential energy stored well away from the crack tip, and finding a direction of

Numerical Modeling of Cracked Arch Dams. Effect of Open Joints during the Construction Phase

Infrastructures
Running a numerical model for a cracked arch dam that takes into account all the particularities of the materials and dam with a high level of detail has a great computational cost involved. For this reason, it is usual to simplify such a model in search
