CE 741 Geomechanics of Stress Deformation

3 Credit Hours

Concepts of volume change and effective stress, stress-strain behavior of clays and sands, stress path and failure conidtions; mechanistic interaction between solids and water, problems in elasticity and plasticity pertaining to stress distribution, elstic, consolidation and secondary settlements, and tolerance limits to deformation levels.


Undergraduate course in soil mechanics.

Course Objectives

The main objective of CE 741 is to introduce the subjects of stresses and deformation of soil media, theories of soil mechanics, and problems in elasticity and plasticity pertaining to earthwork. In this course, students will learn the following:

  • Fundamental Concepts of Effective Stress
  • Stress Distribution in Continuous Media accounting for heterogeneity
  • Elastic Displacements
  • Deformation analysis of non-homogenous media
  • Time-Dependent Settlement and Creep
