Abstract
This paper deals with the determination of the stress propagation in the HH10 type of steel
railroad ties under dynamic loads.
The HH10 type of steel ties were tested for fatigue at the University of Illinois at
Urbana-Champaign. Simultaneously with the laboratory fatigue tests, I was modelling the stress
distribution in the tie due to the dynamic loads with using finite-element
software `ABAQUS´.
After the introduction, the laboratory arrangement of the tie fatigue test
will described in Chapter 2.
Chapter 3 details the steps in building up the finite-element model of the `HH´
railroad ties. In
Chapter 4, the stress pattern and numerical values
for the stresses and displacements of
the tie due to dynamic loads as results of the finite-element program will be
presented. The most important results will be summarized in Chapter 5
