ONLINE COURSE:

SIMULATION OF COMPOSITE MATERIALS WITH ABAQUS

Learn the best strategies for the simulation of composite materials

ACCESS NOW

Discover the most valuable and efficient numerical strategies to get high-quality simulations of composite materials

Understand all the concepts behind the FE models: multiscale modeling, cohesive zone models, periodic boundary conditions, residual stresses, damage modeling…

Save lots of time automating your numerical models thanks to Python scripts in Abaqus

Learn how to fix your simulation if it does not converge, even in the presence of damage and other nonlinearities

Learn how to interpret the results of your numerical models and a lot more tips and recommendations to obtain stunning and meaningful visualizations

The course is meant not only to guide you step by step to develop finite element models, but also to explain why these models are designed in such way 

COMPLEXITY VANISHES WHEN UNDERSTANDING COMES IN!

My name is Miguel Herráez, I am an industrial engineer and Phd in Materials Science.

My first contact with Composite Materials was at the end of my BSc in Mechanical Engineering, performing my final project in the US (West Virginia University).

Thanks to my Advisor (Prof. Ever Barbero), I started to get more and more involved in that field. At that moment, I did not know that it was just the beginning of my scientific career.

I have been studying, testing and developing Finite Element (FE) simulations since 2013, when I started my Phd on numerical modeling of fiber-reinforced composites. I still remember the first years in which I had to learn very little by little about this topic on my own. 

For that reason, I have finally prepared this course with which I want you to learn the numerical strategies for the simulation of composite materials.

You will learn in some hours all what I have learnt in almost 10 years!

The course is based on these three pillars:

WHY – HOW – WHAT

  • Why do we design the model in such or such way? Learn to analyze and design finite element models based on experimental observations supported by theoretical explanations.
  • How do we implement this design into an FE model? Learn step-by-step how to develop the FE models in Abaqus from scratch. In all cases, we will also learn how to generate and customize a Python script to automate and parameterize all the workflow.
  • What is the interpretation of the results? Learn the meaning of each result and how to obtain stunning visualizations. You will get the basis to interpret the results of any other finite element simulation.

You will not only learn to design, build and solve the models covered during the course, but also you will be ready to develop a thousand more types of models!

I am investing a lot preparing this course and I am really proud of the result. I strongly believe that it is going to be super useful for you and a huge time-saver.

    Structure of the course

    • The course follows the bottom-up multiscale strategy and is organized into 3 main chapters: Computational Micromechanics, Computational Mesomechanics and Computational Macromechanics.
    • The course is still “under construction” and the third part (Macromechanics) will be ready over the next months. Once you enroll into the course, you will also have access to all of these contents as soon as they are available.
    • Right now, the chapter on Computational Micromechanics (CMM) and Computational Mesomechanics are ready. CMM is the mainstay to understand and model the deformation mechanisms of composite materials at any length-scale. Whereas Mesomechanics is the perfect framework to simulate real-scale components (mm to cm), and at the same time to reproduce all the failure mechanisms of composite plies and laminates.
    • The course now is made of more than 17 hours organized into more than 110 videos and a lot of additional material: Python scripts, exercises, scientific papers and technical reports, links to specific sections of the documentation, CAE files…
    • The course compiles all what I have learnt about the simulation of composite materials along almost 10 years of thousands of trial-and-errors, extensive literature reviews and many discussions with colleagues in this field.
    • Every 2 hours of the course, you will save 1 full year of testing on your own: aborted simulations, periodic boundary conditions not working, meshing problems, issues with cohesive elements, interpretation mistakes, visualization improvements…

    What my students think of my courses

    “I started your course on composites. You saved my life. I can now speed up a lot of my research.
    It was the best day of my PhD until now.
    Thanks a lot!”

    Giuseppe Romano

    Doctoral Researcher at The University of Manchester (United Kingdom) / Regional Representative at NAFEMS Italy

    “(…) it is a very useful course to understand the interface with Python and the examples provide very clear guidelines on how to use it in the workflow with Abaqus. Regarding the quizzes, they are very nice to put attention to some key points. A lot of material is covered, and quizzes help in refreshing and settling some topics (…). Finally, I would recommend the course to Abaqus users, because it’s a very good intro to Python scripting and impressive results are achieved even with the student edition of Abaqus

    Krishnan Gonesh

    Thank you Miguel, actually, you teach two things at once, Python and Abaqus. Thanks again and again. I am waiting for the simulation of composite materials!!! I will watch the videos again and again […]. A lot of very important steps in building a model in Abaqus/CAE […]. Thanks again!

    Jide Williams

    Graduate Teaching Assistant, University of Denver (USA)

    “By far you have made that anybody can follow the course. You provide all the tools required so that anyone who has ever programmed can follow the course perfectly. Definitely, it is a course made for all levels. I think the course is extremely useful and I would repeat it again for sure. I have felt the course is made taking care of every detail.

    Mario Martín

    Mechanical Engineering student, University of Oviedo (Spain)

    “I have just completed the course Abaqus/Scripting with Python and, firstly, I would like to say congratulations. It has been a really interesting course, from which I take lots of resources to implement. I would like you to make new courses with the advanced topics mentioned at the end (optimization, user interfaces…). I hope to see new contributions and courses soon!

    Andrés Egido

    “Abaqus/Scripting is a powerful tool to automate any task in Abaqus using Python scripts. This means that it is possible to automate and control any action performed in Abaqus and, consequently, save a tremendous amount of time both in the PreProcess and PostProcess stages. […] I highly recommend this course provided by TecnoDigital School and Miguel Herráez.”
