Fatigue testing reveals how materials, components and assemblies behave under cyclic loading. Our unified environment supports fatigue testing, fatigue life testing, resonance fatigue testing, cyclic fatigue testing, axial fatigue tests, torsion fatigue tests, high cycle fatigue testing and accelerated fatigue testing. m+p systems integrate seamlessly into hydraulic, servo-electric, rotating or resonance-based fatigue rigs, providing precise excitation, resonance tracking, multi-sensor data acquisition and high-rate analysis to evaluate fatigue life, structural integrity and failure behaviour.

Fatigue tests often require millions of cycles. Low-frequency loading dramatically increases test duration, slowing both high cycle fatigue testing and low cycle fatigue analysis.

Resonance stimulation and stepped-sine excitation enable fast, efficient cycle accumulation at higher frequencies, with real-time resonance tracking ensuring that each cycle delivers consistent stress levels for reliable fatigue life evaluation.

As fatigue damage accumulates, resonance frequency shifts. Without continuous tracking, excitation drifts away from the optimal stress point, reducing accuracy and extending test duration.

Our control engine maintains resonance through phase-, amplification- or peak-response tracking, ensuring stable excitation and precise stimulation throughout resonance fatigue testing as stiffness and behaviour evolve.

Fatigue behaviour depends on multiple quantities such as strain, force, displacement, torque, velocity or acceleration. Without synchronized acquisition, essential relationships remain unclear.

m+p systems support synchronized, multi-sensor acquisition including strain gauges (quarter-, half-, full-bridge, rosette), force, angle, displacement and acceleration, enabling complete mechanical insight for axial, torsion and rotary fatigue testing.

Fatigue progression causes stiffness loss, resonance drift, phase shift and amplitude changes. Engineers need long-term visibility of these parameters for accurate fatigue testing analysis.

All cycles, frequency shifts, phase changes and response levels are continuously logged and exported, enabling clear trend analysis for fatigue strength tests, damage analysis and failure investigation.

As micro-cracks grow, structures become nonlinear. Detecting nonlinear response patterns requires controlled excitation changes without interrupting the test.

Engineers can apply smooth amplitude increases at constant frequency to reveal hysteresis, stiffness loss and nonlinear behaviour, providing deeper structural fatigue analysis and mechanical integrity testing insights.

Dynamic fatigue tests contain transient events and evolving frequency content that require high-rate raw recordings for deeper evaluation.

High-rate time-domain data can be recorded in parallel with closed-loop control, providing rich FFT, orbit plot and time-domain analysis in the Analyzer for advanced fatigue testing interpretation.

Fatigue behaviour must often be evaluated at multiple discrete frequencies or stress levels.

Stepped Sine excitation provides precise linear or logarithmic frequency steps with defined dwell durations, supporting cyclic fatigue tests, high cycle fatigue testing and accelerated fatigue testing with consistent, repeatable loading.

Fatigue rigs vary widely and frequently include external actuators, climate chambers or additional sensors that need to be synchronized.

m+p solutions integrate seamlessly with external equipment, enabling synchronized monitoring of torque, angle, strain or auxiliary temperatures, making the platform a powerful analysis hub for operational load simulation and custom fatigue testing setups.
