A displacement-free formulation for the Timoshenko beam problem and a corresponding isogeometric collocation approach
Kiendl, Josef; Auricchio, Ferdinando; Reali, Alessandro (Journal article; Peer reviewed, 2017)We present a reformulation of the classical Timoshenko beam problem, resulting in a single differential equation with the rotation as the only primal variable. We show that this formulation is equivalent to the standard ... -
A natural framework for isogeometric fluid-structure interaction based on BEM-shell coupling
Heltai, Luca; Kiendl, Josef; DeSimone, Antonio; Reali, Alessandro (Journal article; Peer reviewed, 2017) -
A simplified Kirchhoff–Love large deformation model for elastic shells and its effective isogeometric formulation
Leonetti, Leonardo; Magisano, Domenico; Madeo, Antonio; Garcea, Giovanni; Kiendl, Josef; Reali, Alessandro (Journal article; Peer reviewed, 2019)Isogeometric Kirchhoff–Love elements have received an increasing attention in geometrically nonlinear analysis of elastic shells. Nevertheless, some difficulties still remain. Among the others, the highly nonlinear expression ... -
Graded-material design based on phase-field and topology optimization
Carraturo, Massimo; Rocca, Elisabetta; Bonetti, Elena; Hömberg, Dietmar Josef; Reali, Alessandro; Auricchio, Ferdinando (Journal article; Peer reviewed, 2019)In the present work we introduce a novel graded-material design based on phase-field and topology optimization. The main novelty of this work comes from the introduction of an additional phase-field variable in the classical ... -
Hierarchically refined isogeometric analysis of trimmed shells
Coradello, Luca; D’Angella, Davide; Carraturo, Massimo; Kiendl, Josef; Kollmannsberger, Stefan; Rank, Ernst; Reali, Alessandro (Peer reviewed; Journal article, 2020)This work focuses on the study of several computational challenges arising when trimmed surfaces are directly employed for the isogeometric analysis of Kirchhoff–Love shells. To cope with these issues and to resolve ... -
Phase-field description of brittle fracture in plates and shells
Kiendl, Josef; Ambati, Marreddy; De Lorenzis, Laura; Gomez, Hector; Reali, Alessandro (Journal article; Peer reviewed, 2016)We present an approach for phase-field modeling of fracture in thin structures like plates and shells, where the kinematics is defined by midsurface variables. Accordingly, the phase field is defined as a two-dimensional ...
