Observations of characteristic markings on the fracture surface of brittle materials can be used to quantitatively describe non-equilibrium fracture. The relationship between quantitative fractography and fracture mechanics is first presented to desc

Presented is the idea of the congruence of binary gaskets generated using modular arithmetic operations on a parent array. It is seen that the binary gaskets of prime orders are nontrivial, while the binary gaskets of nonprime orders are congruences.

Techniques are developed for determining the spatial and size distributions of spherical inclusions in mild steel. The relations between these distributions as found on electropolished surfaces and as found on fracture surfaces are determined. It is

Real-time analysis of the fatigue crack growth process has been achieved by means of phase-sensitive signal detection methods used in conjunction with spectrum analysis. During crack growth, modulations of the displacement signal occur as a result of

The measurement of “chemical shift,” that is, the change in energy of an element's x-ray emission lines with the state of its chemical combination, has been carried out for some years. Of the three major aspects of the technique, two have receive

Fractal geometry is a non-Euclidean geometry which has been developed to analyze irregular or fractional shapes. In this paper, fracture in ceramic materials is analyzed as a fractal process. This means that fracture is viewed as a self-similar proce

The distribution of energy in the ductile fracture of high strength steels is investigated by considering two contributions to the total energy: a dissipative energy term and a dislocation storage term. By means of a material characteristic related t
