POWRE: Multiscale Mechanics of Bone

9753075 Jasiuk这个研究项目研究骨骼的力学，将骨骼视为一种多尺度材料。主要目标是从由数以千计的矿物纤维和胶原基质组成的分子水平(微米级)过渡到有效的连续水平(厘米级)。在这些较大的尺度上，将寻求弹性、非弹性和断裂/损伤状态下的局部场和骨的本构定律。拟议的项目将涉及数值和分析调查，但将与同时在埃默里大学进行的实验保持密切联系。这些实验，以及已经发表的结果，将为我们的计算微观力学模型的验证提供基础。***

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. ***
