Hello,

From the information provided, the cutting speed (velocity of the tool) can be calculated using the formula:

Cutting Speed = Displacement / Time Period

Given that the displacement boundary condition of 0.02 meters was assigned to the tool and the time period in the step module was 0.001 seconds, you can calculate the cutting speed as follows:

Cutting Speed = 0.02 m / 0.001 s = 20 m/s

If, instead of displacement, velocity were assigned to the tool, the time period for the step would need to be adjusted accordingly. To calculate the new time period when assigning velocity, you can use the formula:

Time Period = Displacement / Velocity

If you have the velocity of the tool and want to find the appropriate time period, you can rearrange the formula to:

Time Period = Displacement / Velocity

I hope this helps! Let me know if you need further assistance.

In reply to Journal Club for May 2024: Inverse Design of Mechanical Metamaterials with Nonlinear Properties

Your journal club discussion on the inverse design of mechanical metamaterials with nonlinear properties is both fascinating and informative. You've succinctly outlined the challenges faced in this field and provided insightful solutions, particularly focusing on AI-based strategies. The integration of neural networks and diffusion models into the design process showcases the potential of AI in tackling complex engineering problems.

Your discussion of using neural networks as surrogate models to expedite the design process is particularly compelling. By leveraging the speed and accuracy of neural networks, coupled with an evolution strategy for optimization, you've demonstrated a powerful approach to efficiently navigate the complex design space of metamaterials. The examples provided, showcasing the successful design of metamaterials with specific stress-strain curves, highlight the practical implications of this methodology.

Furthermore, your exploration of diffusion models for inverse design presents an innovative approach to generating metamaterial designs that meet predefined criteria for nonlinear stress-strain responses. The analogy drawn between the progression from still images to moving videos and the advancement from traditional inverse design methods to the utilization of diffusion models effectively conveys the transformative nature of this approach.

Overall, your discussion underscores the significant role that AI, particularly neural networks and diffusion models, can play in advancing the field of mechanical metamaterials. By addressing the challenges inherent in inverse design and offering practical solutions, your insights contribute to the ongoing interdisciplinary efforts to unlock the full potential of AI-driven metamaterial design.

I mentioned Andre in my morning class of "Failure of Materials", when we wnt over some micromechanical fracture models. Speaking of him in the past was not easy.

Thank you very much Amine for sharing this post about André Pineau!
It is a very sad event... but Professor Pineau continues to live in our memories and inspire us!
I've prepared a small photo album with photos of André Pineau that I have.

Amine, your words about Andre are very touching and so true. It is difficult to imagine the field of mechanical metallurgy after him. I was profoundly marked by our discussions, even if we did not always agree scientifically. I had always wanted to initiate something with him, but we were both busy and now it is too late. There's a lot I could say but I would only repeat your words. We have lost a giant. My condolences to Joelle and her family and may Andre finallyt rest in peace in the kingdom of phase diagrams. I am sure that in Heaven, he will convince the residents of the benefits of the local approach which he pioneered and cherished dearly.

Dear Amine,

Thank you for your moving message, I will share it with colleagues. I did not have the chance of being one of his PhD students, but I was lucky enough that he found some interest in my research during my time at Centre des Matériaux, so we had many discussions over the years. He was and will remain one of the most inspiring person I've met. May he rest in peace.
