Fracture is the separation of an object or material into two or more pieces under the action of stress. The fracture of a solid usually occurs due to the development of certain displacement discontinuity surfaces within the solid. If a displacement develops perpendicular to the surface, it is called a normal tensile ***** or simply a *****; if a displacement develops tangentially, it is called a shear *****, slip band or dislocation.Brittle fractures occur without any apparent deformation before fracture. Ductile fractures occur after visible deformation. Fracture strength, or breaking strength, is the stress when a specimen fails or fractures. The detailed understanding of how a fracture occurs and develops in materials is the object of fracture mechanics.

Around 50 percent of orangutans have fractured bones, due to falling out of trees on a regular basis.
Orangutans seem to drift through branches from tree to tree with relative ease. However, almost all orangutans suffer serious falls at least a few times in their lives...
