Dload subroutine for moving load on uic60 rail with thermite weld

Here is a tutorial to explain the Dload subroutine in Abaqus using an example of a moving load (train wheel) on a rail. We show the details of the model and also the model files are provided on the website link at the end of the description. The geometry for each component is created. The material properties were assigned to each component. In the assembly section, we show how they are put together. We used the implicit step as it provides faster results for a longer process compared to the explicit step. We mesh each component based on each component application. In the load and BC section we the necessary details as well as gravity force. We explained each part in detail so you could understand the model.
Dload subroutine
Dload subroutine code is one of the most simple subroutine codes to start learning. It is developed for Abaqus standard and implicit models which covers many applications. One of the advantages of using the implicit solver is its short simulation time. However, it doesn't necessarily mean that it could be after than explicit models all the time. This solver is helpful to solve models which do not have large deformation but require a long time step period. In some cases, such as the movement of train wheels on a railroad track, which requires modelling various components or simulating the movement of a vehicle on the iron rail it is beneficial to use the Abaqus implicit solver. It helps to avoid simulating every component to reduce the computational time. You can use this subroutine to define complex mechanical loads for your model with minimum effort. It is worth mentioning the usage of Dload is similar to VDload and most of the variables are the same.
