  @inproceedings{geiger2020optimal, abstract = {Taking advantage of adaptivity in the field of civil engineering is an ongoing research topic. Integration of adaptive elements in the load-bearing structure is already well established in many other engineering fields. First investigations promise large material saving potentials also in the field of civil engineering, especially when it comes to high-rise buildings or wide spanned structures like roofs or bridges. In times of emission problems and shortage of materials, the potentials of adaptive civil structures open various new possibilities. In the design and optimization process of adaptive civil structures, we address the differences between classical approaches for passive systems and new practices considering adaptivity. By using a suitable actuator placement, it is possible to manipulate the displacements of the structure as well as the force distribution within the structure. Both material and energy savings can be accomplished with an integrated design of the adaptive structure taking into account the actuation, suitable combination of structural design and actuator placement. For demonstration of the differences in the design process and in the resulting optimized structure, we use a small case study on a truss structure, which is inspired by a high-rise building, and consider static loads.}, author = {Geiger, Florian and Gade, Jan and von Scheven, Malte and Bischoff, Manfred}, doi = {10.1016/j.ifacol.2020.12.1604}, journal = {{IFAC}-{PapersOnLine}}, number = 2, pages = {8363--8369}, publisher = {IFAC World Congress 2020, 11.-17.07.2020, Berlin, Germany}, title = {Optimal Design of Adaptive Structures vs. Optimal Adaption of Structural Design}, volume = 53, year = 2020 }

  @article{frohlich2019geometric, abstract = {This contribution proposes a new approach to derive geometrically parameterized, reduced order finite element models. An element formulation for geometrically parameterized finite elements is suggested. The parameterized elements are used to derive models with a parameterized geometry where the parameterized system matrices are expressed in an affine representa- tion. Parametric model order reduction can then be efficiently used to reduce the full order parameterized model to a reduced order parameterized model. The approach shows two beneficial features. First, design studies and shape optimizations can be conducted with parameterized reduced order model of much lower dimension compared to the parameterized, full order model. Second, it is possible to compute sensitivities analytically, and therefore, to avoid the computation of finite differences gradients. The approach is illustrated with two numerical examples. The first example includes a detailed error analysis. The second example is a shape optimization example of an adaptive structure.}, author = {Fröhlich, Benjamin and Gade, Jan and Geiger, Florian and Bischoff, Manfred and Eberhard, Peter}, doi = {10.1007/s00466-018-1626-1}, journal = {Computational Mechanics}, pages = {853-868}, title = {Geometric element parameterization and parametric model order reduction in finite element based shape optimization}, volume = { 63}, year = 2019 }

  @inproceedings{frohlich2018model, abstract = {In this contribution, coupled, parameterized second order systems are considered where the coupled, parameterized system is derived from the assembly of several parameterized component models. Two approaches for the Parametric Model Order Reduction of such coupled systems are presented and compared in a reduced order shape optimization example. In the first approach, the coupled, parameterized system is derived by coupling the parameterized, full order component models. Then, Parametric Model Order Reduction is executed for the coupled system. In the second approach, the parameterized, component models are first reduced independently of their actual mounting situation. Afterwards, the parameterized, reduced order component models are coupled to derive the parameterized, reduced order system model. It is shown that the first approach yields smaller parameterized, reduced order system models. However, the second approach allows to reuse and to recombine the parameterized, reduced order component models arbitrarily. It therefore introduces more flexibility in the modeling process, enabling for example a toolbox based optimization with parameterized, reduced order models.}, author = {Fröhlich, Benjamin and Geiger, Florian and Gade, Jan and Bischoff, Manfred and Eberhard, Peter}, booktitle = {IUTAM Symposium on Model Order Reduction of Coupled Systems, May 22–25, 2018, Stuttgart}, doi = {10.1007/978-3-030-21013-7_11}, pages = {151--163}, title = {Model order reduction of coupled, parameterized elastic bodies for shape optimization}, year = 2018 }
