Creep Measurement Technology

Localized deformation measurement for critical components.

3D Strain has developed a first-of-its-kind technology that measures creep within high-temperature environments using permanent surface features, 3D scanning, and proprietary analysis.

Why 3D Strain

Better creep data supports better lifecycle decisions.

Understanding and accounting for creep behavior is essential in industries such as power generation, aerospace, and automotive to avoid unnecessary costs and ensure reliability and safety of components and structures operating at high temperatures.

Our team helped an OEM save tens of millions of dollars by providing creep-monitoring data that improves Product Lifecycle Management (PLM).

Benefits

Measure what global deformation can miss.

Local Damage Detection

Creep damage can accumulate in small regions, or hotspots, and exceed limits without being detected by global coordinate measurements. Our technology measures localized damage and helps identify early-creeping parts.

Extreme Environments

The surface features require no wires, maintenance, or calibration and are designed to remain with the component through harsh operating conditions.

Non-Contact, Non-Destructive

3D scanning equipment measures localized deformation without touching or destructively sectioning the component.

Passive Monitoring

Measurements use permanent surface features that require no power or continuous connection to a data acquisition system.

How It Works

Three steps from permanent features to actionable strain data.

3D Strain uses patented 3D surface-feature analysis to measure plastic strain. Relative changes in deformation-indicating feature (DIF) geometry are evaluated over time to calculate localized strain.

01

Apply Features

Create DIFs, small bumps or dimples permanently applied to a part's surface during manufacturing or repair.

02

Acquire 3D Scans

Obtain a 3D replication of the DIF region using commercial 3D scanning technology.

03

Measure Deformation

Measure feature locations and produce structural-health metrics using 3D Strain's proprietary software algorithms.

Multi-layered IP protection includes patent, proprietary algorithm, and trade secret.

Test Data

Validated against benchmark mechanical testing.

Numerous tests were performed at a leading structural laboratory using ASTM E8 test specimens and Instron mechanical testing systems. The results showed close agreement with benchmark extensometer output.
