Journal ArticleDOI
Level Set Topology Optimization of Printed Active Composites
TL;DR: The design studies demonstrate the ability of the proposed optimization method to yield a crisp and highly resolved description of the optimized material layout that can be realized by 3D printing.
Journal ArticleDOI
Variational methods for selective mass scaling
Anton Tkachuk,Manfred Bischoff +1 more
TL;DR: In this article, a new variational method for selective mass scaling is proposed, based on a new penalized Hamilton's principle where relations between variables for displacement, velocity and momentum are imposed via a penalty method.
Journal ArticleDOI
Direct and sparse construction of consistent inverse mass matrices: general variational formulation and application to selective mass scaling
TL;DR: In this article, a consistent and sparse inverse mass matrix is built from the modified Hamiltons principle with independent displacement and momentum variables, and a variational mass scaling technique is applied to the RMM.
Journal ArticleDOI
Local and global strategies for optimal selective mass scaling
Anton Tkachuk,Manfred Bischoff +1 more
TL;DR: In this article, the problem of optimal selective mass scaling for linearized elasto-dynamics is discussed and three main optimality criteria, namely eigenmode preservation, small number of non-zero entries and good conditioning of the mass matrix are explicitly formulated.
Journal ArticleDOI
Hybrid-mixed discretization of elasto-dynamic contact problems using consistent singular mass matrices
TL;DR: In this article, a modified Hamilton's principle is proposed for spatial semi-discretization of dynamic contact, which uses displac ement, velocity and momentum as variables, which allows their independent spatial discretization.
