The position papers presented at a seminar held in 1969 at Leeds University are the basis of this report. The papers cover the topics of computers in education, learning systems, planning and management, hardware and engineering, development processes in computer assisted instruction (CAI), and economic problems. The 46 participants at the seminar were from the United Kingdom, Canada, Belgium, Holland, France, and the United States. A summary of the discussion of each topic is presented. Some...

A basic physical explanation, a model, and comments on NDE application of the acousto-ultrasonic (AU) method for composite materials are presented. The basis of this work is a set of experiments where a sending and a receiving piezoelectric transducer were both oriented normal to the surface, at different points, on aluminum plates, various composite plates, and a tapered aluminum plate. The purpose and basic idea is introduced. Also, general comments on the AU method are offered. A literature...

Monolithic ceramic materials have been used in industry for hundreds of years. These materials have proven their usefulness in many applications, yet, their potential for critical structural applications is limited. The existence of an imperfection in a monolithic ceramic on the order of several microns in size may be critical, resulting in catastrophic failure. To overcome this extreme sensitivity to small material imperfections, reinforced ceramic materials were developed. A ceramic matrix...

This thesis presents a Markov model for analyzing the sensitivity of Crusader effectiveness to parametric changes in Crusader capabilities. Crusader activities are represented as finite-state, discrete-time Markov chains. A series of supporting models for some of the Markov model parameters provide for the desired sensitivity analysis on specified engineering characteristics of a Crusader. A Microsoft Excel V7.0 spreadsheet serves as the user interface, computational tool for the models. A...

Contour maps of thickness changes were obtained for three quasi-isotropIc graphite-epoxy plates with central holes, loaded in compression. Thickness changes were determined for six load increments from nearly zero to within a few percent of the failure load. The largest change of thickness occurred near the hole but not at the boundary of the hole. Below 90% of the failure load, the thickness changes were nearly proportional to load. irregularities of thickness changes occurred in zones of...

This study is part of a continuing exploration of the structural behavior of fiber-reinforced composite materials by NASA (Langley). The dual purposes of the present research are to (1) develop a whole-field, high sensitivity optical technique to measure load-induced changes of thickness of composite plates, and (2) measure changes of thickness of three composite plates, each with a central hole of different prescribed size, as a function of applied compressive loads. The specimens were...

The work reported covers three simultaneous projects. The first project was concerned with (1) establishing the sensitivity of the acousto-ultrasonic method for evaluating subtle forms of damage development in cyclically loaded composite materials, (2) establishing the ability of the acousto-ultrasonic method for detecting initial material Imperfections that lead to localized damage growth and final specimen failure, and (3) characteristics of the NBS/Proctor sensor/receiver for...
