Overview of Ceramics Project

چکیده
The background and present plans for the ceramics project are reviewed. This provides the framework SCS0-8300 for the following papers. Introduction As wns discussed previously, an important element in the development of a quantitative NDE technology is the coupling of nondestructive measurement results, failure modeling, and risk analysis to produce an accept/reject criteria. This basic philosophy was first formulated from first principles in the context of a project to produce a quantitative inspection capability for ceramic materials. In this paper, the history of this project is reviewed and the plans for this year's program, whose results you will hear today, are described Accept/Reject Criteria The development of the accept/reject criteria depends on a risk analysis as illustrated in Fig. l. At the top is an equation for the risk, or cost, associated with the selection of particular accept/reject level. That cost consists of three terms: first term, which is associated with false acceptances, a second term, which is associated with false rejections, and a third, constant term associated with fixed costs. In the equation, w represents the cost of failure (lost in false a8ceptance), w1 is the cost of manufacture (lost in false rejection), ar.d b is the fixed costs. The origin of the probability of false acceptance, e , and the probability of false rejection, e1, a~e illustrated in the graph below. There the probability of a given measurement result, y, is plotted both for parts which will survive and parts which will fail. ULATI,ON fHAT WILL SURYIVE SC71J-2G4.; POPULATION THAT WILL rAIL

Sixth millennium BC Dalma ceramics from the northwestern and central Zagros have previously been described as beingimpossible to distinguish using decorative style analysis in spite of the great distance between the two regions. In thisstudy, petrographic (thin section) analysis and a small-scale electron microprobe project was carried out on the ceramicsof the two regions, as well as a small s...
