  text: "Fabrication of curved shells plays an important role in modern design, industry,
    and science. Among their remarkable properties are, for example, aesthetics of
    organic shapes, ability to evenly distribute loads, or efficient flow separation.
    They find applications across vast length scales ranging from sky-scraper architecture
    to microscopic devices. But, at\r\nthe same time, the design of curved shells
    and their manufacturing process pose a variety of challenges. In this thesis,
    they are addressed from several perspectives. In particular, this thesis presents
    approaches based on the transformation of initially flat sheets into the target
    curved surfaces. This involves problems of interactive design of shells with nontrivial
    mechanical constraints, inverse design of complex structural materials, and data-driven
    modeling of delicate and time-dependent physical properties. At the same time,
    two newly-developed self-morphing mechanisms targeting flat-to-curved transformation
    are presented.\r\nIn architecture, doubly curved surfaces can be realized as cold
    bent glass panelizations. Originally flat glass panels are bent into frames and
    remain stressed. This is a cost-efficient fabrication approach compared to hot
    bending, when glass panels are shaped plastically. However such constructions
    are prone to breaking during bending, and it is highly\r\nnontrivial to navigate
    the design space, keeping the panels fabricable and aesthetically pleasing at
    the same time. We introduce an interactive design system for cold bent glass façades,
    while previously even offline optimization for such scenarios has not been sufficiently
    developed. Our method is based on a deep learning approach providing quick\r\nand
    high precision estimation of glass panel shape and stress while handling the shape\r\nmultimodality.\r\nFabrication
    of smaller objects of scales below 1 m, can also greatly benefit from shaping
    originally flat sheets. In this respect, we designed new self-morphing shell mechanisms
    transforming from an initial flat state to a doubly curved state with high precision
    and detail. Our so-called CurveUps demonstrate the encodement of the geometric
    information\r\ninto the shell. Furthermore, we explored the frontiers of programmable
    materials and showed how temporal information can additionally be encoded into
    a flat shell. This allows prescribing deformation sequences for doubly curved
    surfaces and, thus, facilitates self-collision avoidance enabling complex shapes
    and functionalities otherwise impossible.\r\nBoth of these methods include inverse
    design tools keeping the user in the design loop."
