Hopkinson bar testDIC technology
Hopkinson Bar (SHPB) Impact Test

In Hopkinson bar impact testing, Haytham's monocular 3D high-speed DIC better adapts to the spatial and temporal characteristics of such tests, providing a stable technical approach for recording high-speed material deformation.

Displacement Measurement and Reliability Verification of Large-Structure Shaking Table Test

In structural dynamics experiments, the research team used Haytham's monocular 3D high-speed DIC for full-field vibration measurement of a large-scale structural scale model. High-speed cameras were placed outside the model, capturing 3D motion information of the structure surface from multiple views synchronously without physical contact.

Lithium Battery Nail Penetration Test

Haytham integrates DIC full-field strain measurement with infrared thermal imaging under unified calibrated coordinates, observing temperature fields and strain/displacement fields simultaneously in the same coordinate system and time axis — extending characterization from a single quantity to multi-physics collaborative analysis.

High-Temperature Tensile Test of Rebar (Featureless Recognition)

In steel property evaluation, high-temperature tensile testing is an important means of checking heat-resistance strength and plasticity. However, for rebar with rough, reflective and complex-textured surfaces, traditional contact extensometers often fail to work stably; even conventional optical methods require sprayed marking points or speckle patterns, which tend to burn off or peel at high temperature, causing data interruption or increased errors.

Virtual Strain Gauges (DIC): Upgrading Strain Measurement from Bonded Gauges to Virtual Measurement Points

The virtual strain gauge is based on DIC algorithms rather than a physical sensor. The system computes high-precision displacement/strain from images before and after loading, creating virtual measurement points at any location on the specimen surface, with results available in real time or via post-processing.

Microscopic DIC Full-Field Strain Measurement of Earphone Cable: Locating Fatigue Weak Points Under Repeated Bending

Haytham's visual microscopic strain measurement system uses DIC to obtain minute displacement and full-field strain distribution of earphone cables during repeated bending, accurately locating strain concentration and fatigue weak regions — a reference for cable structure optimization, life assessment and failure analysis.

DIC technologyTungsten wire vibration testing
Tungsten Wire Vibration Test

The tungsten wire is thin with low amplitude, making sensor attachment difficult. Haytham's monocular 3D high-speed vision strain gauge, based on monocular 3D DIC, records the entire vibration process, extracts Y-direction displacement and reconstructs mode shapes — suitable for modal frequency identification and flexible structure response analysis.

Three-point bending testVideo extensometer
Three-Point Bending Test of Prefabricated-Notch Metal Specimen

The crack initiation region is small with evident strain concentration, and traditional methods struggle to capture crack-tip evolution. The Haytham system continuously observes strain changes near the crack tip, aiding research on fracture initiation mechanisms.

Cable bridge compressionDIC technology
Bridge Cable Pressing Test

The member has a long span and uncertain deformation modes, making multi-point strain gauge placement difficult. The Haytham system can set multiple gauge sections for synchronized tracking, enabling multi-section response observation and comparative analysis of cable bridges under compression.
