Stresses and Strains in Soils: Elastic and Plastic

A new monograph for my geotechnical readers.  You can download it here.  Abstract is as follows:

Many undergraduate civil engineering students find their required geotechnical courses strange. They enter into a new world of soil classifications, granular mechanics and porous materials, and a raft of empirical formulae. There seems to be little connection between the topics and a unifying theory is hard to find. Other enter geotechnical engineering in the course of their work as equipment suppliers, owners and the like, who may not have specific training in the field and find many of the concepts baffling. This article attempts to approach one of the important topics in geotechnical engineering in a different way. In the past, presentation of theory was just that–presentation–and it was difficult to apply the theory in a practical way except for the simplest of cases. Now, with finite element analysis, this theory can become practical reality. Many practising civil engineers, however, look on FEA as a “black box” where one puts in (hopefully meaningful) data and gets out answers which are at best no more meaningful than the data. Hopefully this article will bridge the gap between the two and make learning the essentials of stresses in soils easier.
