TURN OPERATING LOADS INTO ENGINEERING INSIGHT.
Assess structural durability under repeated loading
A structure that satisfies a static strength check may still require a fatigue assessment. KOMES evaluates the effect of repeated and variable loads on structural details, welded joints and machine components. The objective is to identify critical locations and assess durability for the specified operating scenario.
Define the loading history
The calculation depends on the operating cycle, load amplitudes, number of repetitions and material or joint characteristics. We review measured histories, specified load spectra or an agreed service scenario. Uncertain inputs are identified before a life estimate is interpreted.
Connect the loads with the structural response
FEA provides the response needed for the selected assessment method. Stress definitions and evaluation locations must be consistent with that method, particularly for welded details. We agree on the applicable requirements and document the assumptions used in the calculation.
Support design and operating decisions
The assessment can identify fatigue-critical regions, compare design variants and evaluate the consequences of a proposed operating cycle. Measurements may help establish representative loads or compare the model response with the real structure.
What the report contains
- The loading scenario and number of cycles considered.
- The model, assessment method and relevant material or joint data.
- Results for the agreed details and design variants.
- Interpretation, limitations and recommendations for the next engineering step.
A calculated life is conditional on the input data and method. It is not an unconditional guarantee of service life.
Prepare an enquiry
Describe the component, operating history, intended service life and any observed damage. Mention the drawings, material records and load measurements available. Confidential documents can be provided after an NDA is agreed.
