Linear fracture – a fracture that is parallel to the bone's long axis; Transverse fracture – a fracture that is at a right angle to the bone's long axis; Oblique fracture – a fracture that is diagonal to a bone's long axis (more than 30°) Spiral fracture – a fracture where at least one part of the bone has been twisted
fracture front – the line separating the rock that has been fractured from the rock that has not; fracture tip – the point at which the fracture trace terminates on the surface; fracture trace – the line representing the intersection of the fracture plane with the surface; Griffith cracks – preexisting microfractures and flaws in the rock

Fracture is the appearance of a crack or complete separation of an ... the slope of the linear portion, which is the inverse of the compliance of the material, can be ...
Some fracture zones such as Chile and Valdivia make up large sections of the Nazca-Antarctic plate boundary. Map of the Chile Rise and its fracture zones in Nazca and the Antarctic plates Active Pacific Ocean fracture zones are perpendicular to the mid-ocean ridges (black lines) in orange shaded region. Since the map was prepared ages not shown ...
Fracture mechanics is the field of mechanics concerned with the study of the propagation of cracks in materials. It uses methods of analytical solid mechanics to calculate the driving force on a crack and those of experimental solid mechanics to characterize the material's resistance to fracture.
Such fractures occur in planar parallel sets at an angle of 60 degrees and can be of the same size and scale as joints. As a result, some "conjugate joint sets" might actually be shear fractures. Shear fractures are distinguished from joints by the presence of slickensides, the products of shearing movement parallel to the fracture surface. The ...
A horizontal line would have a plunge of 0°, and a vertical line would have a plunge of 90°. [ 3 ] [ 7 ] A linear feature which lies within a plane can also be measured by its rake (or pitch). Unlike plunge, which is the feature's azimuth, the rake is the angle measured within the plane from the strike line.
