Multi-Axis Strain Gauge Rosette Assemblies for Complex Load Analysis

Strain Stress delivers precision rosette assemblies designed to measure multi-directional strain accurately

Overview

Strain gauge rosette assemblies are advanced sensor configurations used to measure strain in multiple directions at a single point. These assemblies are critical for analysing complex stress states where strain cannot be captured by a single linear gauge. By calculating principal strain and direction, rosette configurations support detailed structural diagnostics, fatigue assessment, and finite element model validation. This page presents an in-depth view of the design, application, and industry use of rosette assemblies, as well as their integration with digital data acquisition systems.
Strain Stress, a B2B company with a growing footprint across North America, supports engineers, manufacturers, and infrastructure teams with precision rosette assemblies that improve measurement accuracy and system performance. Our integrated technologies are built to withstand demanding environments and deliver the clarity needed for high-stakes decision-making. From bridges to aerospace components, we provide the tools and support needed to extract meaningful, actionable strain data from every surface.

Case Studies

Stress Evaluation on Aerospace Fuselage – Texas, USA

A defense contractor used our rosette assemblies on composite fuselage sections to measure in-service loads during flight simulation. The data helped validate stress tolerances and supported FAA airworthiness certification.

An automotive OEM deployed Strain Stress’ rosette gauges in crash testing labs to evaluate fatigue behavior in high-performance aluminum chassis under repeated impact cycles.

Our rosette assemblies were installed on a steel girder bridge to measure stress concentration around fatigue cracks. Integrated with wireless telemetry, the system enabled long-term, real-time tracking that informed rehabilitation plans.
