Tire Compression Deformation Test

In automotive tire compression testing, accurately capturing tire deformation under load is essential for performance optimization and safety improvement. Traditional methods have many limitations and cannot fully reflect tire deformation behavior, making non-contact full-field DIC measurement a more complete choice.

Fatigue Test of Hip Joint Implants

Hip joint implants face complex multiaxial loads in the human body, including compression, tension, bending, and torsion. These superimposed loads make the fatigue behavior of the implant complex and difficult to predict. Traditional strain measurement relies on strain gauges, so non-contact DIC full-field measurement offers a more complete view of implant fatigue performance.

Dual-Device Single-Point Tracking Test of Railway Track

In some field testing tasks, the focus is on displacement results at key positions, together with high requirements for measurement stability and result consistency. This is especially true in complex, space-limited field environments, where dual-device single-point tracking provides stable, repeatable displacement data for the railway track.

Propeller Blade Fatigue Test

In fatigue life verification of propeller blades, traditional strain gauges are limited by difficult installation on curved surfaces, complex wiring, and signal degradation from long-term vibration, making comprehensive, stable measurement hard to achieve. The project team therefore adopted DIC full-field strain measurement.

Bridge Slab Pressing Fatigue Test

Under long-term repeated loading, fatigue damage gradually accumulates inside bridge slabs and may eventually lead to structural failure. Traditional fatigue testing methods rely on contact sensors that must be mounted directly on the slab surface, while DIC full-field strain measurement tracks the fatigue behavior of the whole surface without contact.

Air Spring Fatigue Test

Air springs are widely used in vehicle suspension systems and industrial equipment to provide cushioning and vibration reduction. Because they repeatedly bear dynamic loads in service, fatigue testing is a key step in evaluating their long-term performance. Traditional contact sensors offer limited coverage, so non-contact DIC reveals the deformation distribution throughout the fatigue test.

Virtual Strain Gauge Measurement

Strain measurement is unavoidable in material and structural testing. Traditional resistance strain gauges are mature, but with complex geometries, non-uniform loads, or multi-region observation, bonding is tedious and wiring difficult. Virtual strain gauges based on DIC extract strain at any location without contact for fast, flexible multi-point observation.

Bridge Cable Pressing Test

Cable components in bridges have long spans and uncertain deformation modes, making multi-point strain gauge placement difficult. The Haytham visual strain gauge, based on monocular 3D DIC technology, sets multiple gauge sections and tracks them synchronously, capturing the multi-section response of bridge cables under compression loading.

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

Strain measurement is critical in material mechanics and structural testing. Traditional resistance strain gauges are mature but fail when flexible materials resist bonding, structures are hard to wire, dynamic loading amplifies noise, and fixed points cannot be adjusted. DIC virtual measurement points overcome these limits.

Large-Deformation Measurement of Rubber

In large-deformation testing of rubber, strains often reach hundreds or thousands of percent, with nonlinearity, local concentration, and rebound. Contact extensometers slip or detach under such deformation, corrupting the data. Non-contact DIC tracks the specimen throughout for accurate full-field strain even at extreme elongation.
