A Personal Introduction to Eclipse Chasingndition under which Hertzian ring cracks initiate on glass surfaces. The case of cracking produced by a flat cylindrical punch is also considered and is compared with that due to a sphere. It is shown that ring cracking data obtained with a punch, or less conveniently with a sphere, may be used to d

Characteristics of the Diseased Ankle,nd distribution of flaws or imperfections in the material. In studying the “bulk strength” and other bulk properties of the composite it is generally assumed that these flaws are randomly distributed throughout the material and hence the medium is statistically homogeneous. Therefore, in this type o

Prediction of strength for such materials depends upon understanding the interaction between cracks and the heterogeneous structure of the material. For example, Cherepanov1 using dimensional analysis showed that the strength of a particulate composite with weak

Complications of Total Ankle Arthroplasty,racks. The existence of atomic cleavage in a large class of materials is argued on the basis of the stability of a crack under spontaneous dislocation formation. A qualitative description of lattice trapping of a cleavage crack is given which correlates the effect to the atomic force laws. The deter

Postoperative Care and Follow-Up,ed least action law for brittle fracture. A quantitative physical meaning will be given to the concepts of rest pulse, fracture potential, and penetration depth. A long and a short pulse of equal energy will be compared to show that the above quantities depend on the pulse length and the flaw distri
