Simulating Cast Components Under Cyclic Loading for Fatigue Prediction
In modern foundry and manufacturing, predicting how cast components behave under repeated stress is critical to product reliability. PoligonCast leverages advanced simulation to help engineers anticipate fatigue failure before a single part leaves the foundry floor.
Why Fatigue Prediction Matters
Cyclic Loading
Cast components in automotive, aerospace, and heavy machinery are subjected to repeated stress cycles that gradually degrade material integrity.
Unexpected Failures
Without accurate fatigue prediction, failures occur unexpectedly, leading to costly recalls, safety risks, and production downtime.
Simulation Advantage
Simulation closes this gap before physical prototyping begins, ensuring durability and compliance are validated in advance.
Finite Element Analysis maps stress distribution across complex cast geometries under simulated load cycles.
Accurate material models capture the unique microstructural properties of cast alloys, including porosity effects.
Rainflow counting algorithms translate variable load histories into actionable fatigue damage metrics.
The Role of Simulation
FEA Integration
Material Modeling
Cycle Counting
Casting defects — shrinkage porosity, cold shuts, and inclusions — act as stress concentrators that dramatically reduce fatigue life. PoligonCast's simulation workflow links solidification analysis directly to structural fatigue models.
Detect defect locations early in the design process to prevent costly failures.
Evaluate how defects influence component fatigue life and durability.
Refine gating and risering systems to minimize defect formation during casting.
Confirm design integrity and fatigue resistance before investing in tooling.
