The 16th National Conference on Experimental Mechanics grandly opened at the Fuyue Hotel in Jiaxing, Zhejiang, from April 23 to 25. The event was hosted by the Professional Committee on Experimental Mechanics of the Chinese Society of Theoretical and Applied Mechanics, and co-organized by the Zhejiang Tsinghua Institute of Flexible Electronics Technology, Tsinghua University, and Shanghai Jiao Tong University. XTOP3D was honored to participate in this prestigious gathering as an invited exhibitor specializing in 3D full-field measurement technology, engaging in in-depth technical discussions with attendees regarding the application of DIC measurement technology in the field of solid mechanics.
The National Conference on Experimental Mechanics is the most significant and largest academic gathering in my country's field of experimental mechanics. The conference aims to foster academic exchange among experts and scholars, showcase the latest experimental testing technologies and instrumentation, promote the interdisciplinary integration of experimental mechanics with other fields, and expand its applications in frontier disciplines, engineering technology, and the defense industry.
The conference covered a wide range of topics, including novel methods and technologies in experimental mechanics; measurement techniques for internal mechanical parameters in structures and materials; the development of scientific instruments for mechanics and interdisciplinary research; and education and public outreach in the field. Specialized sessions were held focusing on civil engineering and transportation, biomedical applications, electronic materials, and mechanical manufacturing, alongside events designed to connect with the testing needs of local enterprises.
The XTDIC 3D full-field strain measurement system showcased by XTOP3D—featuring non-contact measurement and full-field data acquisition—supports applications such as tensile, fatigue, vibration, and high-temperature deformation testing. It effectively assists researchers in overcoming testing challenges associated with composite materials—such as anisotropy, large strains, and thermal sensitivity—thereby providing robust support for acquiring experimental data in mechanics testing.
During the exhibition, numerous industry professionals visited the XTOP3D booth to engage in discussions regarding the visualization of measurement results, measurement data accuracy, and equipment operation and application. As a leading domestic provider of 3D strain measurement technologies and equipment, XTOP3D earned high acclaim from attendees for its innovative approach to experimental mechanics testing, mature technical solutions, and extensive project experience.
The XTOP3D XTDIC system effectively analyzes the mechanical properties of materials and the dynamic load performance of structures. It integrates seamlessly with various test rigs and testing machines to measure and acquire data on full-field strain, deformation, displacement, amplitude, and modal characteristics. The system is equipped with comprehensive software for data analysis. By combining hardware and software with proprietary measurement algorithms, it delivers high-quality, highly stable experimental mechanics data.
Based on Digital Image Correlation (DIC) algorithms, the XTDIC non-contact full-field strain measurement system compares images of the test object before and after deformation. It identifies correlated image regions via grayscale analysis to calculate surface displacement and strain distribution, ultimately yielding full-field 3D strain data. Typical applications include material mechanical property testing (Young's modulus, Poisson's ratio, and elastoplastic parameters) and fracture mechanics testing. When paired with a microscope, it enables micro-scale morphology and strain analysis (at micron and nanometer levels) and Finite Element Analysis (FEA) validation. It is also suitable for high-speed deformation measurement (dynamic and transient events) and the testing of strain and displacement in structural components.
In the fields of rock, coal, and civil engineering, the XTDIC system measures stress, strain, and displacement trajectories within the field of view, making it particularly suitable for tests involving large deformations, crack evolution, and dynamic observation. The testing process is fully traceable and evaluable. Common applications include experiments on mining-induced fracture evolution in coal seam overburden, studies on the development patterns of water-conducting fracture zones in mining areas, seismic simulation tests for structures, and concrete crack propagation experiments. By analyzing surface displacement and strain distribution, the system rapidly captures the movement and deformation of rock strata and structures, providing data analysis and theoretical research support for planning, design, and production in civil engineering.
XTOP3D specializes in providing innovative solutions for scientific research. Its products and equipment are widely used in fields such as material mechanics, structural mechanics, and fatigue and reliability testing. They enable full-field measurement of 3D topography, displacement, and strain data during mechanical testing, fully supporting users in establishing and refining capabilities for mechanical testing, simulation validation, and experimental measurement, thereby helping to achieve excellence in research and experimental data.
