Muchas gracias por su generosidad y aporte al conocimiento y entendimiento real de que es la arquitecta. La geometría y la matemática de la superficie de los sólidos es la nueva frontera que con estos trabajos nos ayudan a traspasar, no se imaginan lo valioso de éste conocimiento entendiendo que en la geometría del plano se encuentra el soporte 3d. Gracias.

Congratulations to the authors. I looked for your paper and found it. In my personal opinion I consider that a research like this should be published by an editorial house. So far, your publication can't be used as a reference because it is not published (the paper that appears in the website has no publisher, doi, etc).

This was brilliant! I wish I had such a program to play with... having such a software incorporating Bucky Fuller's Synergetics might help with the problem of doing closed systems, as that is where synergetics begins. Knowing that the angular takeout of any whole body is equal to 360° times the number of vertices minus 720° might prove useful, as this would apply to the topology of the kagome eyes. really wonderful to see this!

Great design and a beautiful overview of the disciplines involved in such a project! I wonder how the auxetic property plays a role in the fabrication and assembly. Does it allow for minimal offcuts in the aluminium plates?
@tachitomohiro1519 3 жыл бұрын
Great work!. Is each module geometrically bistable, so you can program the deployed state? However, it looked to have more degrees of freedom (2DOF?) in the case of real material.
@thedriftery 3 жыл бұрын
No, these units don't automatically deploy to the correct position, however, by moving the unit hub to meet its neighbors, the programmed overall form is accomplished. I have thought of trying to develop bistable units, though I'm not sure it's possible with the kirigami approach. I have 3D printed and other types of re-deployable units. I've been thinking of using bending-active approach to make bistable units, but haven't tried it yet. Actually, after seeing your talk, I'm thinking about creating the primary surface tiling as an auxetic surface, in order to pack it more tightly into the sheet material. At the moment, we only cut flat strips of units for the double-curved versions, but it is still quite costly in terms of waste material on the sheet, unlike the original flat versions. I'd be interested to hear your thoughts sometime.

I like the concept of integrating cladding with structures. Q1. How is each panel modelled when you model the entire system as a space frame? Is it possible that the panel is moment free, or does it require a certain thickness to resist bending? Q2. Usually, cladding has shorter service life than the structure. What is the strategy for refurbishing this integrated structure?
@tachitomohiro1519 3 жыл бұрын
Beautiful work! I understand that the structure needs to keep every panel in tension. How is the prestress be applied to the structure? Will it always have a single mode of self-equilibrium, so the extension of the strut is enough to control the self-stress? If so, what property of the underlying tiling makes it possible?

Thank you for your great presentation! I'm interested in the effect of body forces in this process, compared to external forces at the boundary, especially in the discretized case. What are the major geometrical differences between the discretized expression of those two stress functions? If we change a different discretization strategy, how will it influence the distribution of stresses?
@yu-chouchiang9804 3 жыл бұрын
Thank you for your appreciation. 1. The body forces mask/cover a portion of the curvatures; in a discretized case, the mask only works on the "voids" and leaves the crease untouched. 2. If the different strategy means different mesh connectivity, the results may not effectively reveal principal stresses. I have an obsession with principal stress networks, so I prefer to using circular and conical meshes. However, triangular or hexagonal meshes should also work.

Thank you for the great presentation and paper. I am particularly interested in the load-bearing behaviour along the asymptotic curves (your final chip and banana example). I would like to understand how (or if) your theory can be applied to asymptotic gridshells or if it is only valid for continuous shell. Is what you're describing related to the elongation and compression of the normal fibers in a beam under torsion (helix torsion)? The geodesic torsion along a ruling/asymptotic of a hyperbolic paraboloid is not constant. It is related to the Gaussian Curvature, rather than the straightness (geodesic curvature) of an asymptotic CurveOnSurface. Does this affect the mechanical torsion?

Very clear and fun presentation, Xavier. Really enjoyed it. Could you clarify if i-li-wein surfaces are the only surfaces that offer both funicular and PQ qualities, or are they a subset of a larger family? Looking forward to the discussion today!
@eikeschling9761 3 жыл бұрын
Thank you for the great video! Could this technique be used on any freeform surface. Would be interesting to see how much conventional architectural design would benefit from this technique, and how much overlap of Gaussian curvature we could utilize (of course in an appropriate tolerance).
@alexandersehlstrom6330 3 жыл бұрын
Thanks for your presentation! Why are you cutting not only the contact faces of the node but also the sides? By cutting the sides, you damage the circumferential fibers, which, to my understanding, contributes the strength of the tree branch.

This is beautiful work and a very nice presentation, thank you! Could you comment further on the applications of this research? For example, you mention an architectural application in which the structure is constructed offsite and then deployed. Does the DOF approach also give you instructions for a minimal set of additional supports or braces that will guarantee that the structure will not collapse while in use? What are the other potential physical applications of this research?

Thank you for this nice paper and presentation! I’m curious to know whether the 3D printed results validated to detect any differences with the simulated results? Did you observe any impacts of the fabrication methodology on the results? In particular I’m wondering about any fabrication-introduced defects (delamination etc.) that may have an impact on the performance of the physical form, and how your model might account for these?

Hello. Thank you very much for the presentation and the article. Can you briefly summarize what advantages your method has over more traditional prediction tools such as multidimensional surface fitting from a set of samples.
@kpollux 3 жыл бұрын
Hello. Thank you very much for the presentation and the article. Given the small size of the cell compared to the overall dimensions, have you considered homogenising (e.g. finding equivalent stiffnesses) this structure in order to quickly predict the structural behaviour and thus optimise thickness/pattern/input surface?
@thedriftery 3 жыл бұрын
Hello Nicolas. Thank you. I think what you're describing is one of the desired next steps. Thus far, we've only been working with quadrilateral units (and those constrained to rombuses), so other work is necessary to describe other unit types. The complication comes when you describe a unit that deploys in non-parallel fashion (vs. a more simple parallel deployment). More geometry to solve in order to get to the point you describe, if I understand the question correctly. Thank you!

Very concise and impressive presentation! I have two questions :1. for a discrete Voss surface, should every vertex satisfy the valence of 4? Can this thickening method be applied to different kinds of origami structures? 2.for section 5.1, does the input only contain an arbitrary polyline and a universal offset distance for every section? Can there be more freedom in designing the other direction?
