项目摘要

This project is to establish a new computational approach to the design and manufacture of particulate composites. The performance of a composite changes with many factors, so developing a new composite commonly requires a large number of experiments to optimize the manufacture parameters if a parametric experimental approach is adopted. Through accurately reproducing the complex material processing and testing by virtual experiments, physical experiments can be reliably simulated on the computer, and thus significantly reduce both the material development time and cost. Application of the inclusion-based boundary element method (iBEM) is planned to create high fidelity simulation of the material behavior and will be used for the virtual experiments of the particulate composites. While the principles and methodologies developed can be applied to general composites, this project focuses on lightweight concrete (LWC), which is made of foam particles mixed in a cement paste. Its unique thermal, acoustic and lightweight properties make it an excellent material for energy efficient building envelope. This project will produce a new tool to accelerate the design and development cycle of advanced materials, which will produce significant benefits to our manufacturing industry and thus to the U.S. economy. The multidisciplinary research covering theoretical, numerical and experimental aspects will promote our student research and education in science, technology, engineering, and mathematics (STEM). This project integrates computation, experiments, and micromechanics together to establish a new design paradigm that advances the state-of-the-art of the design of particulate composites in the following aspects: 1) The random particulate microstructure generation algorithm will provide a practical method to construct digital composite materials; 2) The iBEM, simulating each inhomogeneity as an inclusion with an eigenstrain through the Green function technique, will avoid meshing inside the representative volume element (RVE), enable the simulation of 1000 inhomogeneities, and therefore provide a more objective, realistic description of material samples; 3) Interactions of inhomogeneities across two length scales (micron and millimeter) will be evaluated to predict the failure process through the microstructural evolution of the composite, and; 4) The virtual experiments, validated by a few actual experiments, will reproduce the mechanical behavior on computer and accelerate material design and the optimization process of new composite materials. The success of this project will not only establish our LWC design method, but also lead to a breakthrough in computer-aided design (CAD) of particulate composites. In addition, it will demonstrate the iBEM as a new continuum method to study particle interactions of many-particle systems.This award reflects NSF's statutory mission and has been deemed worthy of support through evaluation using the Foundation's intellectual merit and broader impacts review criteria.
该项目旨在为颗粒复合材料的设计和制造建立一种新的计算方法。复合材料的性能随多种因素的变化而变化,如果采用参数试验的方法,研制一种新的复合材料通常需要进行大量的试验来优化制造参数。通过虚拟实验准确再现复杂材料的加工和测试,可以在计算机上可靠地模拟物理实验,从而大大减少材料开发的时间和成本。应用基于夹杂的边界元方法(IBEM)建立了材料行为的高保真模拟,并将用于颗粒复合材料的虚拟实验。虽然开发的原理和方法可以应用于一般复合材料,但该项目专注于轻质混凝土(LWC),它是由泡沫颗粒混合在水泥浆体中制成的。其独特的热学、声学和轻质特性使其成为节能建筑围护结构的优秀材料。该项目将产生一种新的工具,以加快先进材料的设计和开发周期,这将为我们的制造业带来重大好处,从而对美国经济产生重大影响。涵盖理论、数值和实验方面的多学科研究将促进我们的学生在科学、技术、工程和数学(STEM)方面的研究和教育。该项目将计算、实验和细观力学结合在一起,建立了一种新的设计范式,从以下几个方面促进了颗粒复合材料设计的发展:1)随机颗粒微观结构生成算法将为构建数字复合材料提供了一种实用的方法;2)iBEM通过格林函数技术将每个非均匀材料模拟为具有特征应变的夹杂,避免了在代表性体积单元(RVE)内的网格划分,实现了对1000个不均匀材料的模拟,从而提供了对材料样品更客观、更真实的描述;3)评估两个长度尺度(微米和毫米)上的不均匀相互作用,以通过复合材料的微观组织演变来预测失效过程;4)通过几个实际实验的验证,虚拟实验将在计算机上再现力学行为,加速新型复合材料的材料设计和优化过程。该项目的成功不仅将建立我们的轻量化设计方法,还将导致颗粒复合材料计算机辅助设计(CAD)的突破。此外,它还将展示iBEM作为一种新的连续介质方法来研究多粒子系统的粒子相互作用。该奖项反映了NSF的法定使命,并通过使用基金会的智力优势和更广泛的影响审查标准进行评估,被认为值得支持。
