STRESS MEASURMENT - STEEL BRIDGE COMPONENTS (EMAT)

Identifies and measures the magnitude and direction of the combined effect of live and dead loads as well as residual fabrication stress, to assess the remaining strength of steel bridge components. Tailored to provide stress assessment on specific bridge structures, including girders/beams, gusset plates, and pin-and-hanger assemblies.

CODA SM enables total stress measurement in bridge components by taking advantage of the acoustoelastic effect, which describes the influence of stress on the velocity of ultrasonic waves traveling through metallic components.

Merkmale

• Non-contact EMAT technique that can be used on rough, painted, and rusty bridge surfaces without surface preparation.
• Comprehensive evaluation of live load, dead load, thermal, and fabrication-induced residual stresses.
• Custom-designed hardware and software for stress analysis of steel bridge components, including girders/beams, gusset plates, and pin-and-hanger assemblies.
• Stress measurements remain unaffected by temperature variations in the comonent.
• Patented pulser/receiver with optimized EMAT sensors provides <0.8 ns TOF resolution (~2.5 µm-0.0001" in. material thickness) for accurate birefringence and residual stress measurement.
• Custom reports featuring calculated stress measurements, visuals, and raw data export to CSV.
