Direct Micromechanical Simulations for Damage Accumulation in Composite Materials

本研究将发展直接微观力学模拟技术来模拟复合材料的损伤积累。在多轴载荷作用下，基于潜在的微观组织缺陷和微观组织状态的演变，将开发能够评估复合材料变形、断裂、损伤积累和失效的工具。这些模拟将建立微损伤积累的演变与体块复合材料承载能力损失之间的直接关系。

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.
