Prove the part before cutting steel. Run our interactive FEA demo on a real jounce bumper — no sign-up required.
Demo solver. This browser demo uses simplified closed-form estimates for illustration. Production analyses at Croslynk run full nonlinear hyperelastic FEA with Mooney-Rivlin / Ogden material models.
Before any simulation or tooling, every model is checked for manifold integrity, wall thickness and moldability. Here is the live report for the demo part:
The same viewer powers our Modeling page, where you can upload your own STL/OBJ, inspect it and convert formats — free.
Open the model viewer & converter →Typical engineering values used in our demo solver. Production projects use datasheet-verified, batch-tested properties from our rheometer and UTM.
From linear stress checks to full nonlinear hyperelastic and fatigue studies — priced per load case, with a validation report included.
