Multi-objective design optimization of reentrant auxetic model using Lichtenberg algorithm based on metamodel

PurposeThe present paper aims at the multi-objective optimization of a reentrant hexagonal cell auxetic structure. In addition, a parametric analysis will be carried out to verify how each of the design factors impact each of the responses.Design/methodology/approachThe multi-objective optimization...
