ABAQUS FEA Training (Free cantilever beam tutorial)
In “ABAQUS FEA Training Package”, as the first step of this series of tutorials, we’re going to simulate an I-shaped beam under different types of loads and boundary conditions to compare the results with the theory,
To do this, we model the beam in the three-dimensional and then wire-shaped form in Dynamic and static methods. At the end of this course, you will be well acquainted with the graphical user interface and working with ABAQUS.
In the previous part, the training process was explained to you; we also had a brief discussion on finite elements and advantages of ABAQUS. In this tutorial, by solving a problem of beams, we move the module to the module, and while explaining each of them, we complete the simulation of the beam together. Then we repeat this for a few more examples.
The beam is one of the most used structures in the field of engineering, whose main task is to withstand the stresses caused by shear and bending anchors due to the loads on it and the weight of the beam itself.
A beam has a very specific meaning in engineering mechanics: it is a component that is designed to support transverse loads, that is, loads that act perpendicular to the longitudinal axis of the beam. This is the main difference between the beam and the truss; The truss is designed to withstand only axial forces. The beams are used in bridges, structures, aerospace, transportation, and so on.
ABAQUS has an extensive element library to provide a powerful set of tools for solving many different beam problems. Beam theory is the one-dimensional approximation of a three-dimensional continuum. The reduction in dimensionality is a direct result of slenderness assumptions; that is, the dimensions of the cross-section are small compared to typical dimensions along the axis of the beam.
It should be mentioned the demo of this package is available on the Youtube Channel. You can find more Abaqus tutorial packages on the website.

Users ask these questions
In social media, users asked questions regarding Beam simulation in Abaqus, which we answered a few of them; you can see them below.
I. Beam analysis
Q: How can I Bend my BEAM by 45 degrees in ABAQUS By using displacement boundary conditions??
A: Hello,
There are two ways to model a beam: first, you can use the beam element and model the beam as a 2D part which will be a line and apply concentrated force at one of the endpoints. Or, model the beam as a 3D part in which you need to define a reference point for one end of the beam and make the Coupling constraint between them, then apply the Displacement/Rotation boundary condition and apply your desired bend loading.

Best regards.
II. Torque-twist behavior
Q: I’m using Abaqus to create a nonlinear general section, and this requires me to enter the torque-twist behavior of the section. Can somebody help me with this?
A: Hi,
About the torque-twist relationship, you can find information from the ABAQUS documentation. Refer to this link:Â https://abaqus-docs.mit.edu/2017/English/SIMACAEKEYRefMap/simakey-r-torque.htm
