摘要

摘要该出版物的重点是使用熔融纤维制造技术（FFF）的增材制造产品的各向异性特性。对技术实践中使用的五种不同材料进行了测试。这些材料是PLA（聚乳酸）、PETG/CF（聚对苯二甲酸乙二醇酯与碳纤维，复合材料）、PETG（聚对苯二甲酸丙二醇酯）、ABS（丙烯腈-丁二烯-苯乙烯）和ASA（丙烯酸-苯乙烯-丙烯腈）。根据ASTM D638通过拉伸试验验证机械性能。测试由数字图像相关方法进行补充，以定位具有最高负载转移的区域。结果表明，试样具有明显的各向异性。各向异性力学性能也通过数字图像相关（DIC）得到了证实。

Use of Digital Image Correlation in Predicting Mechanical Properties of Parts Made by Additive Manufacturing

Abstract The publication is focused on the anisotropic properties of products of additive manufacturing using a Fused Filament Fabrication technology (FFF). Five different materials used in technical practice were tested. These materials are PLA (polylactic acid), PETG/CF (polyethylene terephthalate-glycol with carbon fibre, composite material), PETG (polyethylene terephthalate-glycol), ABS (acrylonitrile butadiene styrene), and ASA (acrylic styrene acrylonitrile). Mechanical properties are verified by tensile testing according to ASTM D638. Testing is complemented by a digital image correlation method to locate the areas with the highest load transfer. The results have shown clear anisotropic properties of the test specimens. Anisotropic mechanical properties were also confirmed by digital image correlation (DIC).
