  Advance Track Substructure Course Syllables

  The Course Aims and Scope:

  The main goal of the course presentation is the more accurate investigating of dynamic behavior of the ballast and subgrade materials as well as introducing the relevant suitable material models. In part of the course, the analytical methods for railway track analysis will be introduced.

  

  

  The course syllables

  1. Reviewing the Vibration Theory

  · Free and forced vibration with and without damping(hysteresis and viscose)

  · Principles of vibration measurement

  · Systems under the transient forces

  · System under the harmonic forces

 

  2. Wave Propagation in Elastic Solids

  · Wave propagation in elastic bar

  · Wave propagation in infinite and semi infinite elastic solids

  · Body and surface waves

  ·

  3. Dynamic behavior of Subgrade Materials

  · The granular material behavior under the transient dynamic loading

  · Cyclic three-axial test

  · Resonant column test

  · Cyclic plate loading test

  · Dynamic field tests

 

  4. Subgrade Dynamic Bearing Capacity

  · Foundation dynamic bearing capacity

  · An introduction to soil liquefaction

 

  5. An introduction to Soil Plasticity and Critical State Soil Mechanic

  · An introduction to soil plasticity- plastic stress and strain

 

  6. Introducing the plastic constitute lows for dynamic and static analysis of railway subgrade

  7. Introducing the analytical and numerical methods for railway track analysis

  8. An introduction to application of numerical method in railway track substructure analysis
