A variational approach to effective models for inelastic systems
Ghina Jezdan, Sanjay Govindjee, Klaus Hackl
Given a set of inelastic material models, a microstructure, a macroscopic structural geometry, and a set of boundary conditions, one can in principle always solve the governing equ…

Model-free data-driven inelasticity in Haigh-Westergaard space -- a study how to obtain data points from measurements
Kerem Ciftci, Klaus Hackl
Model-free data-driven computational mechanics, first proposed by Kirchdoerfer and Ortiz, replaces phenomenological models with numerical simulations based on sample data sets in s…

A novel class of electro-mechanical metamaterials for stress reduction through electric fields
Mischa Blaszczyk, Klaus Hackl
While most previous developed metamaterials only consider a single physical effect, we introduce a novel class of electro-mechanical metamaterials, which allows a direct controllab…
