Abstract

The objective of this study is to find the optimal geometries for foldcore configurations that are subjected to quasi-static loads and high-velocity impact. It adapts a set of independent design parameters to describe the configuration and details the implementation of a numerical process that organises repetitive simulations. The simulation set-ups are validated against experimental data and fed into parameter-variations and iterative optimisations. As objective function for the optimisations the absorbed energy per unit mass is chosen. This thesis is purely simulative and does not incorporate experiments. Experimental data used for calibration is taken from outside sources. Its main result is a comprehensive set of correlations between the design parameters and the criteria for performance and the characteristics of optimum designs.
