AxiFEA
2D axisymmetric finite-element analysis
Axisymmetric stress analysis of shafts, hubs, shrink fits and seals, with contact and friction, solved in your browser.
Product pages are in English.
Highlights
- 8-node quad and 6-node triangle elements with load stepping and Newton-Raphson iteration
- Shaft-to-sleeve contact for interference fits, with Coulomb friction for press-out forces
- Four presets: shouldered shaft, shrink-fit hub, friction press-out and a rubber seal in its groove
- Von Mises, total, radial and axial displacement fields with deformed shape and live convergence
- Save and reopen your inputs on your computer or in your cloud
A question it answers
What is the peak stress in the fillet at this shaft shoulder under the applied load, and how much does increasing the fillet radius reduce it?What you put in
Shaft and optional sleeve dimensions, shoulder position and fillet radius, per-body material (modulus and Poisson's ratio), global mesh size and a local refinement region, boundary conditions including prescribed axial displacement, applied pressure or edge force, number of load steps and a deformation display scale.
What you get
Von Mises stress contour, deformed shape at a chosen scale, nodal stress values, and a live convergence chart per load step and iteration.
