Predicting fatigue performance of additive manufactured parts - ERP Spain.com - España y América Latina

 

Working with additive manufactured parts empowers the production of increasingly complex designs and enables distributed manufacturing. But predicting the fatigue performance of additive manufactured parts is challenging. The manufacturing process induces multiple local factors that cannot be separated. Therefore, the interaction and influence of these factors cannot be described by mathematical modeling. Hence, today, it is too laborious to estimate the fatigue life of 3D printed safety-critical components.

 

 

Siemens has developed an innovative methodology to predict the impact of the manufacturing process on the fatigue performance of additive manufactured parts. Integrated into an efficient durability solver, Simcenter 3D software leverages the power of machine learning technology.

 

This virtual approach avoids potentially hundreds, if not thousands of tests, by using machine learning together with a limited test set, resulting in a model that can interpolate/extrapolate for untested conditions.

 

 

 

- Integrate machine-learning material model in the open durability solver environment

- Consider different AM process-induced factors that influence fatigue

- Apply to safety-critical structural components

Expand your reach and accurately predict the correct point of failure and fatigue life, whereas conventional methods fail.
