Direct Micromechanical Simulations for Damage Accumulation in Composite Materials

这项研究将开发直接的细观力学模拟技术来模拟复合材料中的损伤累积。将开发能够根据潜在的微结构缺陷和多轴载荷下微结构状态的演变来评估复合材料的变形、断裂、损伤累积和失效的工具。这些模拟将在微损伤累积的演化和块体复合材料承载能力的丧失之间建立直接关系。

This research will develop direct micromechanical simulation techniques to model damage accumulation in composite materials. Tools will be developed that are capable of evaluating the composite material deformation, fracture, damage accumulation and failure based on the underlying microstructural defects and the evolution of the microstructural state under multiaxial loading. These simulations will establish a direct relationship between the evolution of the microdamage accumulation and the loss of load-carrying capability of the bulk composite material.
