Full-Field Strain DIC Measurement of Steel Beam in Compression

In steel beam compression testing, beyond the data related to load-bearing capacity, in-depth analysis is usually required in combination with the deformation distribution on the member surface, local anomalies and response changes. This information can reveal the buckling risk and deformation trends that may occur during loading. However, traditional methods usually rely on a small number of measurement points, and the data between points are discrete, failing to fully reflect the response of the entire member.

Haytham DIC technology can break through this limitation, recording and outputting the strain distribution on the member surface in real time through full-field strain contour maps. Compared with traditional methods, DICprovides continuous and comprehensive deformation data throughout the entire loading process, capturing every detail to obtain more complete structural response information. With this full-field strain monitoring, testers can not only focus on local deformation but also comprehensively analyze the performance of the entire member under compression loads.

This technical advantage is reflected not only in more accurate local damage analysis, but also in more comprehensive data support for overall performance evaluation. Whether analyzing the deformation distribution or identifying potential buckling regions, Haytham DIC provides a more precise and reliable data source for structural testing.
