Summary

Porous cellular structures constitute a new class of materials having a unique microstructure and properties and therefore special testing considerations are required in order to generate reliable design data. One of these anomalies has been referred to as edge effects. These effects result from the large scale macrostructure in these materials which requires a relatively large sample size for testing in order to obtain accurate property measurements. The impetus for this work was to evaluate these edge effects and propose a simple model to predict their magnitude.
