LS-DYNA | Concrete Cylinder Compression Test - CSCM Concrete model Step by step

LS-DYNA is a powerful finite element analysis software widely used for solving a diverse range of problems, including structural, thermal, acoustic, blast, and impact analyses. It is particularly effective in simulating concrete behavior through various specialized models. However, setting up simulations in LS-DYNA can be challenging, especially for beginners. In this guide, we will demonstrate how to simulate a concrete cylinder compression test using the Continuous Surface Cap Model (CSCM), identified as MAT_159 in LS-DYNA.
Software Requirements:
LS-PrePost: An advanced interactive program for preparing input data and post-processing LS-DYNA results.
LS-DYNA Program Manager: A utility to manage LS-DYNA simulations.
Understanding the CSCM Model (MAT_159):
The CSCM model is designed to represent concrete behavior under various loading conditions. Accurate simulation requires the determination of appropriate parameters for this model. For detailed guidance on parameter selection and model calibration, please refer to the paper: doi.org/10.339...
LS-DYNA Sample Model:
A sample LS-DYNA model for the concrete cylinder compression test is available for download at the following link: drive.google.c...
This tutorial provides step-by-step instructions on initiating LS-DYNA simulations, which can be beneficial for both beginners and experienced users.

Welp, UA-cam knows I like computational simulations, so I cant be mad at this random video popping up in my feed...
In my uneducated, unprofessional, unsolicited opinion though....it appears the concrete test cylinder has broken. 😁
Interesting software though!

You're welcome ^^. You're right, the concrete test cylinder is subjected to compression load until failure.

@@tranhan1405 The stress cells were interesting and all, but what grabbed my eye was the voids it rendered. I dont know if it was simply the material separating, or bits that would have 'blown out' as they crumbled in a real world test. But seeing it modify the mesh like that was pretty cool!
