Fatigue Ninja Friday (#14) Element Type and Discretization Effects
Simulation is always a balancing act between accuracy and time. We challenged our intern to benchmark the many options: Should you use linear or quadratic elements? Reduced integration? Hybrid formulation? Quads or tets? Is your mesh sufficiently refined or over-refined? What is the impact on durability? Enjoy this session to learn the winners in this review and discussion of lessons learned so you can go straight to the best practice on your next project.
Fatigue Ninja Friday (#15) EIE and 6 Channels
The forces and moments acting on a rubber part may occur in all 3 coordinate directions, so that there are in general 6 channels of input (3 forces and 3 moments) to consider in a fatigue analysis. This presentation shows how a recording (obtained from track testing or from multi-body dynamics simulation) of these load inputs is rapidly analyzed to obtain strain history and fatigue life. Additionally, computational performance of the workflow is documented including disk space, compute time and solution accuracy. The workflow enables a direct analysis of recorded road load data that executes quickly and gives accurate results.
Fatigue Ninja Friday (#16) Ozone Attack
This course explains how to characterize and simulate ozone attack in Endurica. Ozone is a trace gas that strongly reacts with some rubbers to produce surface cracking following exposure and is often seen on old tire sidewalls or old rubber hoses. Ozone cracking can limit useful product life, even when mechanical cycles operate below the mechanical fatigue threshold. View this presentation to help you use Endurica's software to understand how ozone will impact your products.
Fatigue Ninja Friday (#17) Python Scripting with Endurica
Take advantage of customized and automated workflows with scripting in Endurica. This webinar introduces the basics of accessing and managing Katana analysis files via python. No prior python experience is assumed. Practical examples of automation include running a DOE (design of experiments) to find best option material properties and for post-processing and visualization of analysis results. A further example shows an engine mount application involving the analysis of 144 different road load signals. Our new Katana release is optimized for use with the python scripting language – this course will show you how much easier scripting can make your life!
