Machine-learning-assisted multiscale topology optimization of functionally graded superimposed lattice structures
Prashant Kumar Gupta, Jonathan Stollberg, Dominik Schillinger +1
Functionally graded lattice structures enable lightweight designs with spatially tunable stiffness and density, but their use in multiscale topology optimization is limited by the…

On the Localization of Checkerboarding in Multiaxial Stress Regions under SIMP Penalization
Iulian Paunel, Jonathan Stollberg, Dominik Schillinger
Checkerboard patterns are a well-known numerical artifact in density-based topology optimization using the Solid Isotropic Material with Penalization (SIMP) method and linear finit…

A study on nodal and isogeometric formulations for nonlinear dynamics of shear- and torsion-free rods
Thi-Hoa Nguyen, Bruno A. Roccia, Dominik Schillinger +1
In this work, we compare the nodal and isogeometric spatial discretization schemes for the nonlinear formulation of shear- and torsion-free rods introduced in [1]. We investigate t…
