Vic-2D 7.2.66 is a specific build within version 7 of the Vic-2D digital image correlation (DIC) software developed by Correlated Solutions, Inc. Released as part of the ongoing updates to the Vic-2D suite (initially launched in 2022), this iteration focuses on refinements to core analysis algorithms, user interface stability, and integration with the iris graphics engine. Vic-2D is a non-contact, full-field measurement tool for in-plane displacements and strains on planar specimens, widely used in materials testing, mechanical engineering, and research. It processes images from a single camera to deliver sub-pixel accuracy (down to 0.01 pixel displacement resolution) and strain resolutions as low as 10 microstrain, supporting applications like tensile testing, fracture mechanics, and fatigue analysis.
The software is particularly valued for its ease of use—no calibration is required for strain computation—and its ability to handle specimens from microns to meters. As of October 2025, version 7 remains the current major release, with builds like 7.2.66 incorporating minor bug fixes and performance tweaks based on user feedback from the Correlated Solutions forum.
Key Features in Vic-2D 7.2.66
This build builds on the foundational enhancements of version 7, emphasizing data visualization and post-processing efficiency. While detailed changelogs for exact build numbers are available via the Correlated Solutions support portal (requiring login), the following highlights core and updated features drawn from release documentation:
| Feature | Description |
|---|---|
| Optimized Correlation Engine | Advanced subset-based algorithms for full-field 2D displacement (u, v) and strain (ε_xx, ε_yy, ε_xy) computation at every pixel. Supports strains up to 2000% with high-speed processing for dynamic events. |
| Iris Graphics Engine | Integrated high-resolution visualization tool for exporting publication-ready PDFs, multi-page plots, and 4K MP4 videos. Includes scalable fonts, isoline contours, and FEA/DIC data overlay for validation. |
| Virtual Strain Gauge (VSG) Tool | Real-time strain extraction at user-defined ROIs, with customizable gauges for targeted measurements during or post-analysis. |
| Apply Function & Time Filters | Custom equation builder for derived variables (e.g., principal strains) and integrated temporal filtering to reduce noise in time-series data. |
| Microscope & SEM Integration | Built-in distortion correction for microscopic imaging and drift compensation for SEM data, enabling hybrid optical-electron microscopy workflows. |
| Post-Processing Enhancements | Improved data export to CSV/Excel, batch processing for multi-image sets, and automated hot-spot detection for strain concentrations. Build 7.2.66 specifically addresses minor UI glitches in multi-monitor setups and faster ROI selection. |
