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!

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
  • Computational Micromechanics is the mainstay to understand and model the deformation mechanisms of composite materials starting at the constituents 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.
  • Computational Macromechanics combines a set of modeling assumptions that make possible the numerical analysis of large components and composite structures (scale of meters).
  • The course is made of more than 26 hours organized into more than 170 videos and a lot of additional resources: Python scripts, exercises, scientific papers and technical reports, links to specific sections of the documentation…
  • 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…

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!

    What my students think of the course

    “I have just completed the Simulation of Composite Materials with Abaqus course. I have to say this has been such a great course from the very beginning till the end. Very well presented, explained and structured, combining theory, references, methodology, and practical case studies, with the thinking process capturing the essence of the topic. This course and the knowledge you share makes me want to know even more and dive deeper. I have really enjoyed this course and I am hoping to see more content and courses on composites. I would highly recommend this course. The value and content that is presented in the course saves countless hours of research and struggle

    “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
