How to model repetitive loading in Plaxis 2D?

Written by Gouw Tjie Liong. Posted in Geotechnic, Note and Discussion

A graduate student from Texas A&M University asked:
I’m currently working on a project related to Rail Embankments. How a repetitive/ cycling loading can be simulated in a typical FEM model (I’m using PLAXIS 2D) considering the effect of fatigue.

My answer:
Use HS small soil model, cyclic loading can then be simulated by choosing dynamic analysis and the loading vs time can be created by making a text file first in Notepad (left column is time, right column is magnitude of loading).
