AFS Members Only WebinarLow-alloy steel castings are important components in structures for heavy mobile equipment. It is important that proper finite element models are created to determine fundamental characteristics of the component.
This AFS Members Only Webinar will outline key steps that are essential for determining if a low-alloy steel casting is adequately designed for the anticipated duty cycle. In this case, the duty cycle of the component has been broken down into a set of static load cases that will be used as inputs for the numerical models.
The key steps for constructing a proper finite element model include:
- Geometry creation in CAD (Solidworks)
- Importing the geometry into FEA software (ANSYS)
- FEA pre-processing
- FEA post-processing.
FEA pre-processing includes mesh creation and initial model setup with proper constraints and boundary conditions. FEA post-processing typically consists of determining the components mean stress, stress range, von Mises stress, and deflections. Using these results, an engineer can determine fatigue life using the Modified Goodman approach along with determining adequate safety factors for strength, fatigue, and deflection.
This presentation outlines the steps mentioned above and how proper FEA drives important engineering decisions.
The AFS Members Only Webinar will begin at 1 p.m. CST.
