• Abstract:
  This report describes investigations towards development of general finite element procedures for nonlinear analysis of multicomponent track support systems idealized as one-, two- or three- dimensional problems. It also considers perhaps the most significant aspects of any solution procedure; namely, the stress-strain or constitutive behavior of materials in the structure. Here attention is given to both testing and modelling of improved and appropriate models; the testing is carried out by using new advanced testing devices for 'solids' (wood, ballast, subballast and subgrade soil) and interfaces between these materials.
