ABSTRACT
When analysing experimental results related to soil behaviour, undergraduated students are facedwith a common difficulty of establishing links betweenmany aspects, such as drained and undrained paths, the response of normally consolidated and overconsolidated soil samples, the meaning of undrained strength and many others. One possibility to circumvent this difficulty is to provide the reader, from the beginning, with a simple but robust conceptual framework, and for this reason reference is made to the Critical State Theory.
