In the context of a global digital revolution across various industries, the manufacturing sector has also begun to advance the digitalization of its entire product range, gradually transmitting products in the form of digital flows, internationally referred to as MBD (Model-Based Definition). The concept of MBD was proposed in the early 21st century, and with the enhancement of software and hardware technologies, as well as advancements in semiconductor-based industries, the evolution of MBD into the concept of digital twins has flourished. Fundamentally, a digital twin is a dynamic representation of the past and present behaviors or processes of a physical entity in a digital format, which helps improve enterprise performance. Creating a digital twin mainly focuses on two key areas: - The information requirements for the design of digital twins and the product lifecycle—from asset design to the on-site use and maintenance of assets in the real world; - The creation of enabling technologies that integrate real assets with their digital twins, allowing measurement data to flow in real-time with operational and transactional information in the core systems of the enterprise. Digital twins have become a benchmark for future industrial development; however, the precision issues between measurement and simulation have always constrained their progress! DIC (Digital Image Correlation) technology has undoubtedly become a focal point for the development of digital twin technology as a breakthrough for this bottleneck. DIC technology can perform full-field optical measurements, and when used at the measurement end of digital twin technology, its advantageous characteristics are significant. Especially with the emergence of the new FE-DIC (Finite Element Digital Image Correlation) technology, which directly calibrates and computes based on CAD documents, significantly reducing or eliminating the use of calibration plates in traditional DIC measurements, using MESH grids as the basis for calibration, and directly integrating simulation with actual measurements, truly achieving "virtual-real integration." This lecture will focus on FE-DIC technology and "virtual-real integration," using the products of the authoritative representative in this field, the French company EIKOSIM, as an example to discuss the future development directions and possibilities of digital twin technology.

In contrast to temperature, vibrations need to be handled in very small increments. It can be difficult to control very tightly, so we recommend starting at 2 g and increasing by 2 g at a time. The dwell time also depends on you and your understanding of the product. There should be enough stabilization time, so ten minutes is usually used. You continue to strengthen until you see what you consider to be a failure, and then continue monitoring and data recording.

Remember that there is no perfect way to run HALT. Here are some basic methods to keep in mind. HALT is actually a series of tests. You should have multiple samples available for testing, ideally preparing one sample for each test in the series. From a purist's perspective, the best way to start is to test in a single environment, and then run in a combined environment for comparison.

The measured displacement is directly projected onto the finite element model provided by Reynolds, as shown in Figure 4. As expected, the measured opening motion of the door outward and at the ends is more significant than that on the inside. These results can also be discovered by specifically examining the comparison with the wire sensors. To this end, a virtual displacement sensor (in green in Figure 4) was created using EikoTwin's displacement sensor creation function, positioned on the mesh at the actual location of the physical sensor. Figure 5 shows the comparison between the two sensors during the initial loading steps.

Digital image correlation (DIC) is a non-contact method for measuring the three-dimensional surface displacement field of parts by capturing images from two digital cameras during testing. This technique is based on the assumption of image gray level conservation. The measurement field is directly represented on the three-dimensional surface model used for finite element simulation. The measurement analysis shows that the sheet material undergoes three stages of deformation:

The three-dimensional grid can provide a three-dimensional displacement field and deformation field. It can also detect, monitor, and measure the appearance and propagation of cracks during specialized tests conducted on instrumented bending specimens by studying maps. The obtained mapping allows for a clear visualization of the appearance and propagation of cracks during the tests, and quantitatively measures their evolution.
