Application Cases

Drop-weight impactHigh-speed camera
Pyrite Drop-Weight Impact Test

In pyrite drop-weight impact tests, capturing dynamic deformation under high-speed impact is essential for understanding impact toughness. Traditional methods struggle with precision and speed in such fast, complex events. Non-contact DIC measurement records the full process and delivers reliable full-field strain data.

Vibration DIC Test of Outdoor Air Conditioner Unit

When an air conditioning system starts, runs, and stops, each part generates corresponding stress and vibration. Without detection and control, severe vibration not only creates more noise but also accelerates fatigue damage to the compressor, piping, and related parts, shortening the service life of the outdoor air conditioner unit. Vibration DIC testing helps find and correct such problems early.

Wall Panel Projectile Test

The wall panel projectile test is a common method for simulating wall panel material behavior under high-speed impact. In this highly dynamic, high-strain-rate environment, traditional strain measurement struggles to provide accurate full-field data, so a technique with high-speed, non-contact full-field capability is essential.

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

In structural dynamics research on bridges, dams, and high-rises, vibration testing is key to evaluating structural safety and performance. Contact sensors like accelerometers, displacement meters, and strain gauges are complex to deploy and few in number, so DIC strengthens displacement measurement in shaking table tests.

Hopkinson Bar (SHPB) Impact Test

Hopkinson bar (SHPB) tests pose tough measurement challenges: deformation occurs in microsecond time windows, space around the specimen is limited, and loading is sudden with concentrated energy.

Full-Field Strain Measurement of Aerogel Foam in Compression

Aerogel foam has ultra-low density, high porosity, and strong non-uniformity, so compression brings local collapse and layer-by-layer compaction.
