WEB LIMIT: probabilistic platform for fatigue assessment

Wednesday (27.05.2020)
11:30 - 11:50 Room 2
Part of:

LIMIT is an in-house, phyton-based fatigue assessment software seamlessly connected to the FEM solver. The presentation is focused on the defect-based approach module.

Main features:

1. fatigue strength defined by K-T diagram, El-Haddad and Murakami formulation

2. defect population defined by statistics of extremes

3. designed for a non-specialist user, for either the design or quality control phase

Unique features:

4. defect population is a local information and can be different for each node.

5. defect population can be derived directly from a manufacturing simulation (e.g.: casting process)

6. statistical size effect is considered


Emphasis will be given on the interconnections between the manufacturing process and the defect population(s).
