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

我们正在为相关解决方案公司的3D立体显微镜成像系统(VIC-3D™Micro)提供案例，以准确地原位测量显微复合材料样品的位移和应变，这是任何其他现有设备无法实现的。该设备是唯一可商业化的数字成像系统，能够消除复杂的非径向光学失真，这些失真可能会严重影响应变测量，从而提供准确的数据。 所要求的设备非常需要，以支持来自四所不同加拿大大学(赖尔森大学、多伦多大学、滑铁卢大学和安大略省理工学院)的五名共同申请者的研究项目。PIS正在进行高影响的研究，涉及在许多工程应用中使用的新出现的复合材料的表征和建模，其中评估不同尺度下的力学性能和渐进破坏模式是一个关键挑战。我们的战略是将所要求的3D Micro DIC系统与申请者的红外热像相机测试设置结合使用，以更全面和深入地表征不同规模的复合材料中的全场应力/应变和损伤演变。由于这种测试设置及其使用的独特性，这可能会导致申请者各自的研究计划取得突破。 PIS各自研究计划的实验部分将为30名研究生提供关于所要求的微观想象系统的培训机会，也使他们对复合材料的复杂机械行为有一个基本的了解。这些技能对未来的工程工作以及加拿大的材料和制造业都是可取的。此外，由于PIS参与了一些正在进行的合作研究项目，调查可能使用所需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.
