Novel Numerical Methods for Additive Manufacturing 3D Printing of Dissimilar Materials

该项目旨在推进异种材料零件增材制造的基础知识。为了实现这一目标，我们将开发数值方法来模拟不同材料的分层过程，特别关注分层过程中不同材料的相互作用以及它们与材料源的相互作用。我们的方法将是：通用性强，可应用于研究各种材料的相应本构关系.能够预测。不同材料的粘附能力。增材制造（AD），也称为3D打印，具有通过3D打印生产大型工业部件的潜力。电子束增材打印可以生产大型金属零件，同时也可以生产大型塑料零件。在增材制造中，零件是通过分层工艺生产的，其中最终零件是多层材料的积累。异种材料的AD将是制造业的巨大兴趣的自然发展。在这个项目中，我们将开发异种材料AD的基础知识。我们的目标是推进分层不同材料的知识，重点是分层过程中两种材料的相互作用。除上述相互作用外，我们还将考虑其与材料来源/供应商的相互作用。项目完成后，我们的目标是采用数值方法对具有项目摘要中所列功能的不同材料的AD进行建模。

This project aims to advance the fundamental knowledge for additive manufacturing of parts with dissimilar materials. To achieve this, we will develop numerical method(s) to model the layering process of dissimilar materials, paying special attention on the interactions of dissimilar materials during the layering process and their interactions with the source(s) of the material(s).Our method(s) will be:-1. Generic and can be applied to study a wide range of materials with the appropriate constitutive relations.2. Able to predicti. the adhesion capabilities of dissimilar materialsii. the resulting strength of the composite partsAdditive manufacturing (AD), also known as 3D printing, has the potential of producing large industrial parts through 3D printing. Electronic beam additive printing can produce large metal parts, while large plastic parts can also be produced. In additive manufacturing, parts are produced by the layering process, where the final part is accumulation of multiple layers of materials. AD of dissimilar materials will be the natural development of great interests in the manufacturing sector.In this project, we will develop fundamental knowledge for AD of dissimilar materials. We will aim to advance the knowledge of layering dissimilar materials, focusing on the interactions of the two materials during the layering process. In addition to the above interactions, we will also account for their interactions with the source(s)/supplier(s) of the materials.The aim upon completion of the project, will be to have a numerical method(s) to model AD of dissimilar materials with capabilities listed in the Project Summary.
