IEEE Task Force Report: Brittle Fracture in Nonceramic Insulators
IEEE Power Engineering Review, 2002A description of the composite insulator brittle fracture phenomenon suitable to allow correct diagnosis of a failure is provided. The paper reports on the number of brittle fractures that have occurred around the world and contains specific empirical data surrounding composite insulator brittle fractures in the United States.

The Role of Surface Forces in Fracture
1986The role of surface forces in fracture is considered by incorporating the contribution of the adhesive forces between the crack walls into the net mechanical driving force. It is shown that attractive surface forces lead to a threshold stress intensity below which a crack will heal.

Soil Deformation and Fracture Under Tensile Forces
1989The general theory of fracture of elastic/plastic materials is summarized and important implications for soil mechanics are highlighted. Soil properties which affect its fracture behavior are discussed, with particular emphasis on the interactions between soil structure and moisture relations.

Application of Ultrasonic Force Microscope to Fracture
1997Ultrasonic force microscope (UFM) has been applied to the detection of subsurface defects in HOPG samples1. The advantages of UFM over the conventional scanning acoustical microscope (SAM) is the capability of nanoresolution for subsurface images, without the wavelength limitation of the SAM.

Reflections on the Insertion and Fracture Forces of Microneedles
Current Drug Delivery, 2017The use of microneedles for transdermal drug delivery is a feasible alternative to injections and tablets. As different types of microneedles are being developed from a variety of materials, it is important to understand their insertion and fracture forces.

Fracture Processes Induced by Forced Fluid Percolation
1992The theory of the rupture processes induced by excess fluid pressure is reviewed. After a brief overview of some fracture mechanics principles, the theory of hydraulic fracturing is summarized. Then, shear failure mechanisms are discussed. Some examples of microseismicity and ground deformation associated with forced fluid flow, including magma ...
