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.

Though more parameters used for quantifying the effect of crack in structural component plane strain fracture toughness is the frequently used one.
At present, a single stress or strain fracture criterion cannot explain the failure fracture behavior under the complex stress state of a magnesium alloy material.
The tensile strength, Young's modulus, and nominal strain fracture of the scaffolds were obtained by averaging the values from five samples.
The fracture mechanics parameters taken into considerations were those for the AISI 1022 steel: for Forman equation c = 1.447 x [10.sup.-12], n = 3.6, m = 1 (Forman et al., 1967); the plane stress fracture toughness [K.sub.C] = 110 MPa [m.sup.1/2], respectively the plane strain fracture toughness [K.sub.IC] = 77 MPa [m.sup.1/2], the threshold stress intensity factor range under which the crack do not propagates [DELTA]K = 1.5 MPa [m.sup.1/2].
The plane strain fracture toughness and tension tests of the steels investigated were carried out by Krasowsky and Krasiko [12] at the Institute for Strength Problems (Kiev, Ukraine).

Drawing on a compendia of sources assembled by Hudson and Seward (cited in (6)), representative values of plane strain fracture toughness, [K.sub.Ic], can be collected and estimates of its variability made.
The purpose of fracture toughness testing is to determine the value of the critical stress intensity factor, or plane strain fracture toughness [K.sub.C].
McClintock and Leguilon [3, 4] offered strain fracture criteria when plastic zone at crack tip is taken into account and stresses [[sigma].sub.[infinity]] are calculated:
The relatively low strength of PE necessitates a thick pipe wall, which in turn favors plane strain fracture. 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.
