Abstract:

This final report is presented in two parts, and is in continuation of two previous reports prepared under this contract. Part 1 contains details of the development of finite element procedures for nonlinear analysis of track support structures. It provides the user options for using one-, two- or three-dimensional idealizations, and options for using various elasticity and plasticity based constitutive models. The numerical predictions are verified with respect to a number of closed-form solutions and field problems. Part 2 contains comprehensive testing of 'solids' such as wood, ballast, subballast and subgrade soil and interfaces; these materials were collected from the UMTA Test Section. The solid media were tested by using truly triaxial or multiaxial testing devices, whereas the interfaces between wood and ballast, concrete and ballast and ballast and subballast were tested by using a new cyclic multi-degree-of-freedom shear device. The laboratory test results were used to derive appropriate constitutive models for use in the finite element procedures.
