As global manufacturing output continues to rise, industry is continually striving for increasing efficiency of production while simultaneously balancing the reduction of waste and emissions, typically under the directive of government regulations. Recent examples of minimizing the use of raw materials while maintaining favorable mechanical performance can be seen in the fields of metal coated polymers (MCPs). The advantages of incorporating MCPs into the manufacturing industry are widespread, including directly reducing emissions associated with shipping, increased product lifespan compared to conventional plastic components, and reliability for mission critical applications, where reduced weight and maximum stiffness are imperative. The proposed work is comprised of two interconnected research endeavors that share the mutual goal of increasing the ease of implementation of MCP technology into existing design practices. Firstly, creating accurate multi-physics modelling methods to be able to predict the complex behavior of MCP materials will allow designers to computationally test the performance of proposed designs. significantly reducing the number of physical prototypes required for component validation. The second goal of this research is to develop advanced design methodologies for the manufacturing of MCP products, including but not limited to MCP topology optimization and developing the process of the redesign of metal components for use with MCPs. The partnership will feature a three-year project, with three full-time graduate students and several on-site internships at General Dynamics Mission Systems.

随着全球制造业产出的持续增长，工业不断努力提高生产效率，同时平衡减少废物和排放，通常是在政府法规的指导下。最近在金属涂层聚合物（mcp）领域可以看到最小化原材料使用同时保持良好机械性能的例子。将mcp纳入制造业的优势是广泛的，包括直接减少与运输相关的排放，与传统塑料组件相比，产品寿命更长，以及关键任务应用的可靠性，在这些应用中，减轻重量和最大刚度是必不可少的。拟议的工作由两个相互关联的研究努力组成，它们的共同目标是增加MCP技术在现有设计实践中的实施难度。首先，创建精确的多物理场建模方法，以便能够预测MCP材料的复杂行为，这将使设计师能够计算测试所提出设计的性能。显著减少组件验证所需的物理原型数量。本研究的第二个目标是为MCP产品的制造开发先进的设计方法，包括但不限于MCP拓扑优化和开发用于MCP的金属部件的重新设计过程。该合作伙伴关系将以一个为期三年的项目为特色，其中包括三名全日制研究生和通用动力任务系统公司的几名现场实习。
