Fracture Mechanics of Elastic Composites
- 33 Downloads
Fracture mechanics of elastic composites is the study of cracks in elastic composites bodies. 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. There are three fracture modes for crack propagation: mode I of fracture (opening mode) (a tensile stress normal to the plane of the crack), mode II of fracture (sliding mode) (a shear stress acting parallel to the plane of the crack and perpendicular to the crack front), and mode III of fracture (tearing mode) (a shear stress acting parallel to the plane of the crack and parallel to the crack front).
In the first part of the entry, we shall determine the incremental elastic state produced in our prestressed orthotropic, linear elastic body using complex potentials. The representation of elastic fields by...
