A phase-field-based graded-material topology optimization with stress constraint / F. Auricchio, E. Bonetti, M. Carraturo, D. Homberg, A. Reali, E. Rocca. - In: MATHEMATICAL MODELS AND METHODS IN APPLIED SCIENCES. - ISSN 0218-2025. - 30:8(2020), pp. 1461-1483. [10.1142/S0218202520500281]
Abstract:
In this paper, a phase-field approach for structural topology optimization for a 3D-printing process which includes stress constraints and potentially multiple materials or multiscales is analyzed. First-order necessary optimality conditions are rigorously derived and a numerical algorithm which implements the method is presented. A sensitivity study with respect to some parameters is conducted for a two-dimensional cantilever beam problem. Finally, a possible workflow to obtain a 3D-printed object from the numerical solutions is described and the final structure is printed using a fused deposition modeling (FDM) 3D printer.
