"FOREWARD
Methods of engineering analysis and problem solving have been changing rapidly in recent years. When I graduated from engineering school (1950), graphical methods of solving problems in structural engineering were very much in vogue. The ability to draw sharp lines, measure areas with a planimeter and to do accurate drafting rapidly were sought after and useful skills in the design office and were, hence, taught in engineering schools. With the advent of improved mechanical calculators, numerical methods became more popular. Engineering courses were redesigned around the use of these mechanical calculating machines …
…
With the advent of modern electronic digital computers, their general availability and increased accessibility, fundamental changes have taken place in the practice of engineering and in the curriculum of schools of engineering …
…
The development of programmable pocket calculators, is probably going to bring about a fundamental change in the relationship of the engineer to the problem solving process …
…
The computational routines presented in the following pages were prepared during the years 1974-1976 …
…
The list of programs presented is by no means a complete list of the possible uses of programmable pocket calculators in geotechnical analysis. They have primarily chosen because I needed them in my work. They do, however, represent a reasonable sampling of problems encountered in geotechnical engineering. It is hoped that they may be found useful to the profession."
