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 ... -
Optimal control of multiphase steel production
Hömberg, Dietmar Josef; Krumbiegel, Klaus; Togobytska, Nataliya (Journal article; Peer reviewed, 2019)An optimal control problem for the production of multiphase steel is investigated that takes into account phase transformations in the steel slab. The state equations are a semilinear heat equation coupled with an ordinary ...
