Dynamic short crack growth in cortical bone
Technology and Health Care, 2006It is well known for almost half a century that bones contain microcracks. Very little is known about the crack growth behaviour of very small cracks, e.g. the stage before they become macroscopically long. The aim of this work was to investigate the dynamic crack growth behaviour of sub-millimetre microcracks in cortical bone.

Fatigue Crack Growth of Short Cracks in an ALMGSI Alloy
1989The behaviour of short fatigue cracks in the range of 300–1000 μm has been investigated in a precipitation hardened AlMgSi alloy aged to maximum hardness. The grain structure was equiaxed with a diameter of 100 μm.

The Journal of Adhesion, 1975
Abstract In the lap joint shown in Figure 1, the sheets of elastic material AB and CD are originally plane and joined completely over their mating surfaces with a very thin adhesive of fracture energy R, When tensile forces F are applied to test the joint, cracks propagate from the points C and B to cause eventual separation of the elastic sheets.

Crack deflection: Implications for the growth of long and short fatigue cracks
Metallurgical Transactions A, 1983The influences of crack deflection on the growth rates ofnominally Mode I fatigue cracks are examined. Previous theoretical analyses of stress intensity solutions for kinked elastic cracks are reviewed. Simple elastic deflection models are developed to estimate the growth rates of nonlinear fatigue cracks subjected to various degrees of deflection, by ...

Figure 1 shows crack growth data from the propagation of a surface crack in a 2024-T351 aluminium alloy specimen subjected to mode I fatigue loading. The loading conditions are: peak stress 325 MPa, stress ratio of 0.1 and fatigue life of 139,500 cycles.
