strain fracture

a·vul·sion frac·ture

a fracture that occurs when a joint capsule, ligament, or muscle insertion or origin is pulled from the bone as a result of a sprain, dislocation, or strong contracture of the muscle against resistance; as the soft tissue is pulled away from the bone, a fragment (or fragments) remains attached to the soft tissue of the bone.
Synonym(s): strain fracture

avulsion fracture

A fracture which occurs when a fragment of bone is forced out of the surrounding bone by tightened ligaments due to a strain or intense muscle contraction against resistance.

strain frac·ture

(strān frak'shŭr)
The tearing off, by a sudden force, of a piece of bone attached to a tendon, ligament, or capsule.

The purpose of fracture toughness testing is to determine the value of the critical stress intensity factor, or plane strain fracture toughness [K.
McClintock and Leguilon [3, 4] offered strain fracture criteria when plastic zone at crack tip is taken into account and stresses [[sigma].
Unfortunately PE--like many thermoplastics--also has relatively little resistance to plane strain fracture at crack speeds, exceeding 100m/s and temperatures below 0[degrees]C.
Whilst strength and the stability of drawing determine the energy per unit volume of material in a relatively simple way (it is their product), the contribution of this energy to total fracture resistance must depend on the ability of plane strain fracture resistance: this must be large enough to generate a large (high volume) plane-stress plastic zone.
International Standard ISO 17281 defines a fracture mechanics test capable both of evaluating plane strain fracture resistance at up to 1 m/s and of precisely resolving a transition temperature.
