3D Stero Micro-Imaging Measurement System (3D Micro DIC) for in-situ characterization of advanced composites and new emerging smart materials

我们正在为Correlated Solutions，Inc.的3D立体显微镜成像系统（维克-3D™ Micro）提供案例。精确地测量，在现场，位移和应变的微观复合材料试样，这是无法达到与任何其他可用的设备。拟议的设备是唯一的商业可用的数字成像系统，能够消除复杂的非径向光学失真，可以严重偏置应变测量，从而提供准确的数据。 所要求的设备是非常需要的，以支持来自四个不同的加拿大大学（瑞尔森，多伦多大学，滑铁卢大学和安大略理工大学）的五个共同申请人的研究计划。PI正在进行高影响力研究，涉及许多工程应用中使用的新兴复合材料的表征和建模，其中评估不同尺度的机械性能和渐进失效模式是一个关键挑战。我们的策略是使用所要求的3D Micro DIC系统与申请人的红外热成像相机测试设置相结合，以更全面和深入地表征不同尺度下复合材料的全场应力/应变和损伤演化。由于这种测试设置及其使用的独特性，这可以导致申请人各自研究计划的突破。 PI各自研究计划的实验部分将为30名研究生提供机会，接受所需显微成像系统的培训，并为他们提供对复合材料复杂力学行为的基本理解。这些技能对于未来的工程工作以及加拿大的材料和制造业来说都是可取的。此外，由于专业人员参与了一些正在进行的合作研究项目，调查可能使用所要求的设备的其他先进材料，因此还可以培训更多的HQP。

We are making a case for a 3D Stereo Microscope imaging system (VIC-3D™ Micro) from Correlated Solutions, Inc. to accurately measure, in-situ, displacements and strains of microscopic composite specimens which is unattainable with any other available equipment. The proposed equipment is the only commercially-available digital imagining system able to remove complex non-radial optical distortions that can severely bias strain measurements and thus providing accurate data. The requested equipment is highly needed to support the research programs of five co-applicants from four different Canadian universities (Ryerson, University of Toronto, University of Waterloo and University of Ontario Institute of Technology). The PIs are conducting high impact research involving characterization and modelling of new emerging composite materials used in many engineering applications where assessing the mechanical properties and progressive failure modes at different scales is a key challenge. Our strategy is to use the requested 3D Micro DIC System in conjunction with the applicant's infrared thermography camera test setup to have a more comprehensive and in-depth characterization of full-field stress/strain and damage evolution in composites at different scales. This can lead to breakthroughs in the applicants’ respective research programs because of the uniqueness of such test setup and its utilization. The experimental component of the PIs’ respective research programs will provide the opportunity for 30 graduate students to be trained on the requested micro-imagining system, also providing them with a fundamental understanding of the complex mechanical behaviour of composite materials. Such skills are desirable for future engineering jobs, and for Canada's materials and manufacturing sector. In addition, since the PIs are involved in a number of ongoing collaborative research projects investigating other advanced materials for which the requested equipment may be used, additional HQP may also be trained.
