Rubber large deformationDIC technology
Large-Deformation Measurement of Rubber

In large-deformation mechanical testing of rubber, specimens often exhibit strains of hundreds or even thousands of percent, with obvious nonlinearity, local tension concentration and rebound. Traditional contact extensometers tend to slip, detach or restrict free deformation under large deformation, making truthful, reliable data hard to obtain. For this challenge, Haytham Technology's DIC system provides a stable, mature non-contact solution for large-deformation rubber measurement.

Material tensile testingVideo extensometer
1500℃ Tensile Test of Carbon/Carbon Composite

In 1500℃ high-temperature tensile testing of carbon/carbon (C/C) composites, the material is exposed to strong radiation, high heat flux and complex atmosphere. Traditional contact extensometers and strain gauges tend to fail, peel or introduce additional load, failing to reflect the true constitutive behavior. For this extreme condition, Haytham Technology's monocular 2D video extensometer, combined with high-temperature speckle technology, provides a stable, reliable non-contact measurement solution for high-temperature mechanical testing of C/C composites.

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.

Rebar tensile testingHigh-temperature extensometer
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.

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.

Titanium-nickel alloy compression
TiNiNb Titanium-Nickel Alloy Compression Test

The specimen is small and prone to buckling; traditional fixture installation is difficult and loading interference is significant. The Haytham system stably records strain evolution during axial compression without contact.

Aluminum rod tensile testingVideo extensometer
Unmarked Tensile Test of Aluminum Rod

Traditional image correlation algorithms tend to fail on samples with extremely weak texture. The Haytham system optimizes the image acquisition and processing chain, stably tracking gauge section deformation under low-texture conditions — suitable for polished specimens and composite interface analysis.
