Fatigue and Fracture Mechanics Simulation Services

Component failures are often not due to a single event, but due to accumulated damage caused by a cyclic loading history or a series of loading histories.

Fatigue Failure Prevention via Correlation of Simulation to Testing

Strain Gauge and Vibration Measurement and Analysis

SimuTech Group has expertise in vibration and strain measurement. Many of our customers who come to us for fatigue analysis or life prediction of their components and systems don’t fully understand the loading and constraints that their hardware experiences in the field.

SimuTech Group’s test engineering team can instrument your hardware with accelerometers and/or strain gauges and measure the response to real world loading. The test data can then be correlated to FEA models. Our simulation consulting engineers work closely with our test engineers and often use these correlated FEA models to accurately predict fatigue life and damage accumulation under the customer’s correlated operating conditions.
