摘　　要：One of the innate features of many natural structural materials is excellent damage tolerance enabled by hierarchical anisotropic architectures.Highly anisotropic structural materials usually demonstrate high performance in one direction,but become weak in other directions.For example,the osteon of compact bone is longitudinally aligned with high anisotropy,making the bone difficult to break but still easily to be split[1–3].Similarly,abalone shell shows superior crack resistance owing to its hierarchical structure.
