Homogenized shell element-based modeling of low-velocity impact response of stainless-steel wire mesh

In this study, we describe the development of a shell model-based macro-scale approach for a stainless steel 304 wire mesh using Hill's yield criterion and elasto-plastic material behaviors. The constants for orthotropic elastic-material response and the parameters for non-linear behavior were determined from experimental tests. For validation and comparison, the results obtained using this macro-scale model were compared with the experimental data obtained from drop-tower impact tests and the simulation results from a meso-scale model. The comparison highlighted that the macro-scale model of the wire mesh is more suitable for large-size simulations.

Automated summary

This study developed a macro-scale approach for studying the mechanical properties of stainless steel 304 wire mesh using a shell model, with material parameters determined from experimental tests. The comparison with experimental data and simulation results showed that the macro-scale model is more suitable for large-size simulations.
