Course Objective

Soil mechanics topics are now took up with critical state theories more than classical theories in the world. However unsaturated soil mechanics topics are more popular in the geotechnical engineering area because it allows that engineers may solve some geotechnical problems economically and realistic. It is aimed in this lecture to do graduate students to have useful knowledge about critical state soil mechanics and unsaturated soil mechanics.
