Fig. 7

Microstructural strain field overlaid on a digital micrograph of a cortical bone specimen that was loaded to a macroscopic strain of 1500 με in the horizontal direction. Each color represents a specific level of maximum principal strain as indicated by the legend. The local microstructural strain field is highly heterogeneous and strain is found to localize around osteocyte lacunae as well as between lacunae. Local perilacunar strain reaches peaks of over 15,000 με in this specimen. Subsurface lacunae affect the local strain fields in a similar manner as lacunae on the surface. The arrows indicate osteocyte lacunae below the machine surface of the specimen. Original magnification: 500 ×.
