9753075 Jasiuk This research program investigates the mechanics of bone, treating bone as a multiscale material. Major goal lies in the passage from the molecular level comprising thousands of mineral fibers and collagen matrix (micron scale) to an effective continuum level (scale of centimeters). Local fields and constitutive laws of bone for elastic, inelastic, and fracture/damage regimes, on those larger scales will be sought. The proposed project will be involved numerical and analytical investigation but close contact with the experiments being concurrently conducted at Emory University will be maintained. These experiments, along with already published results, will provide a basis for verification of our computational micromechanics modeling. ***

9753075 Jasiuk该研究计划调查骨的力学，将骨作为多尺度材料。 主要目标在于从包含数千种矿物纤维和胶原蛋白基质的分子水平（微米级）到有效的连续水平（厘米级）。 局部领域和弹性，非弹性和断裂/损伤制度，在这些较大的尺度上骨的本构关系将寻求。 拟议的项目将涉及数值和分析研究，但与埃默里大学同时进行的实验保持密切联系。 这些实验，沿着已经发表的结果，将提供一个基础，验证我们的计算细观力学模型。 ***
