Spot the 3 key types of nonlinearities in product performance
Discover how nonlinearities can impact physical test results
Discover the terms and processes for including nonlinearities in simulation
Discover nonlinear analysis so that these concepts can be employed in upfront design decision-making
Real-world problems are rarely linear or static. Nonlinearities often impact the prediction of a product's behavior in unpredictable ways. These add uncertainty and risk to decisions made from either virtual or physical test results for engineers and designers who don't understand them. We will summarize simply and clearly the process of identifying and planning for the 3 key types of nonlinearity in product performance so that all attendees will be able to spot them, again in both physical as well as virtual testing. We will teach you how to account for nonlinearities in testing, but the remaining focus will be on nonlinear simulation covering processes, terms, and troubleshooting. While we will use Simulation Solutions for illustration, the concepts covered will be valid for any simulation software attendees.
Engineers & Designers who want to reduce the risk in upfront design decisions.
Vince Adams has been a consultant, instructor, and advocate for finite element analysis (FEA) in product design for over 20 years. He has written 3 books on the subject, including the popular Building Better Products with Finite Element Analysis, as well as numerous articles for Desktop Engineering and Design News magazines. Vince has been an invited speaker and instructor with engagements all over the United States, as well as in Europe, South Africa, and Asia. He was nominated by peers to lead the founding of NAFEMS North America (www.nafems.org) and was selected by this organization to be on the Founding Member list for the international Professional Simulation Engineer program based on his career contributions to the simulation industry. Prior to focusing on simulation, Vince was a design engineer and engineering manager accumulating numerous patents, many due to novel uses of FEA (at the time) and learning firsthand the importance of properly applied simulation for improved innovation.
David Weinberg is currently a Senior Software Developer for Autodesk and was the former President/CEO and Founder NEi Software from 1991 to 2014 until the acquisition of NEi by Autodesk in May 2014. He was the primary developer for NEi Nastran and currently leads the team of developers for Autodesk Nastran. Prior to forming NEi Software he worked as an Aerospace Engineer for Boeing for over 15 years. He holds a Bachelor of Science degree in Aerospace Engineering from Embry-Riddle Aeronautical University. He has over 30 years’ experience in FEA simulation working as a user, developer, and instructor.
In this class, Autodesk Simulation experts will examine the commonly understood, and often published, methods for modeling welds in finite element analysis (FEA). The true nature of welds, their physics, material characteristics, and failure modes will be reviewed in the context of what you can and can’t expect from simulation. Best practices for static weld sizing using FEA, primarily Nastran In-CAD, and Inventor will be revealed. Evaluating welds for fatigue will also be reviewed to ensure participants are using state of the art simulation for all their welding applications.
Post processing results from finite element analysis (FEA) solutions is essential to understanding whether your design passes or fails based on your engineering criteria. There are many options available for checking the design integrity, such as different types of stress plots. There are also several contour options such as nodal, elemental, max, and average. During this course we'll explain the importance of all these options and what to look out for to make sure the results are accurate.
When performing finite element analysis, the quality of your mesh dictates the accuracy of your results. With the advances in automatic meshing technology, this quality is often overlooked. This class will focus on key topics such as selecting the correct mesh size, using mesh refinement, and interrogating the element quality to make sure you can be confident in your results.
This lab will focus on getting started with Autodesk Nastran In-CAD software inside of Inventor 2016 software. Participants should have an understanding of finite element analysis (FEA) and the preferred participants are currently using FEA in their jobs. We will explore the Ribbon, Browser, and different analysis types. We will have a few workflows for basic users that are looking to crest the initial hurdle when learning new software, as well as a few examples for the more advanced users who are familiar with FEA software.
