项目摘要
Analysis, Manufacturing, and Mechanical Testing ofStitched Sandwich CompositesAbstractThe team from the University of Utah and Georgia Tech will conduct an integrated analytical, manufacturing, and experimental investigation of the fundamental mechanical behavior of stitched sandwich composites with through-thickness reinforcement in their foam core. The proposed research program will enhance the knowledge and understanding of the mechanical and damage responses including creep and other time-dependent behavior. To that end, research is proposed in three major areas:Manufacturing: Development of non-normal stitching concepts for sandwich structures will be investigated under a variety of multi-axial loadings, including bi-axial and pure interlaminar shear. Stitching for enhanced compression behavior will be investigated by optimizing the characteristics of perforated stitched sandwich structures.Analytical and Computational: Multi-scale micromechanical and structural models will be developed to simulate the mechanical behavior of stitched sandwich composites with emphasis on both short-term and long-term time-dependent responses. Different finite-element structural modeling approaches, using shell, continuum, and cohesive fracture elements, will be used to simulate the material and structural responses including time-dependent and damage growth.Experimental: Standard and non-standard test procedures will be developed and performed to examine the mechanical behavior of stitched sandwich composites and structural components under combined mechanical and environmental conditions.The proposed inter-university collaboration between the three PIs and their graduate and undergraduate students will ultimately promote and enhance the research and educational infrastructure at both sides. The composite education and research center CERC at Georgia Tech will be part of the proposed activity. Its students and other faculty will tremendously benefit from enhancing its capability in the area of sandwich composites. Undergraduate and graduate students from underrepresented groups will be part of this new research project. The authors are planning to host conference sessions and a summer workshop on using sandwich composites for practicing engineers in the areas of automotive, aerospace and civil infrastructure. The educational activity on sandwich composites, based on this research, will be integrated in two composite courses at the undergraduate and graduate levels. The web will be also used to produce an educational module for design of sandwich composites.
摘要来自犹他大学和佐治亚理工学院的研究小组将对在泡沫芯中加入厚度增强的缝接夹层复合材料的基本力学行为进行综合分析、制造和实验研究。拟议的研究计划将加强对机械和损伤响应的认识和理解,包括蠕变和其他随时间变化的行为。为此,提出了三个主要研究领域:制造:在各种多轴载荷下,包括双轴和纯层间剪切,将研究三明治结构的非正常拼接概念的发展。通过优化穿孔缝合夹层结构的特性,研究缝合增强压缩性能的方法。分析和计算:将开发多尺度微观力学和结构模型来模拟缝合夹层复合材料的力学行为,重点是短期和长期的时间依赖性响应。不同的有限元结构建模方法,使用壳、连续体和内聚断裂元素,将用于模拟材料和结构的响应,包括时间依赖性和损伤增长。实验:将制定和执行标准和非标准测试程序,以检查缝合夹层复合材料和结构部件在综合机械和环境条件下的力学行为。上述三间大学的合作计划,将有助推动和加强双方的研究和教育基础设施。乔治亚理工学院的复合材料教育和研究中心CERC将是拟议活动的一部分。其学生和其他教师将极大地受益于提高其在三明治复合材料领域的能力。来自弱势群体的本科生和研究生将成为这个新研究项目的一部分。作者计划为汽车、航空航天和民用基础设施领域的实践工程师举办关于使用三明治复合材料的会议和夏季研讨会。基于这项研究,三明治复合材料的教育活动将被整合到本科和研究生两门复合材料课程中。该网站还将用于制作三明治复合材料设计的教育模块。
