Direct Micromechanical Simulations for Damage Accumulation in Composite Materials

本研究将发展直接微机械模拟 技术来模拟复合材料中的损伤累积。 将开发能够评估 复合材料的变形、断裂、损伤累积和 基于潜在微观结构缺陷和 在多轴载荷下的微观结构状态的演变。 这些模拟将建立一个直接的关系， 微损伤的累积和损失的演变 散装复合材料的承载能力。

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.
