摘要
The effect of randomly removing members of a three-dimensional truss material on the Young's modulus and compressive strength has been calculated numerically. The results indicate that this structure is more tolerant to this type of defect than open-cell foams. (C) 2001 Acta Materialia Inc. Published by Elsevier Science Ltd. All rights reserved.
