Theoretically, composites promise strength several thousand times greater than steel. So why don’t we have composite materials everywhere? The practical design of composites severly limits their capabilities. Once you understand the practical limits, it provides a useful design guide for how to apply composites and maximize their advantages.
Why are ship structures so labor intensive to design? Engineers need to anticipate multiple methods of failure, which makes a lot of work. The trick of efficient structural analysis focuses on recognizing which methods of failure are likely in each scenario. This article reveals six major methods of structural failure, with examples of common applications. Because it will be the failure mode you didn’t consider that ultimately leads to catastrophe.
We all want to feel good about paying for engineering analysis. Sometimes the best answer drives us to maximize value, rather than minimize cost. In those cases, you do better to go beyond basic safety and search for enhancements. Today we discuss four engineering tasks where you can maximize your value. Extract every last drop of knowledge from your engineering project.
An experienced engineer doesn’t have some magic button to deliver great FEA. Masters of FEA trade-craft hoard many little tricks and nuggets of wisdom to deliver better FEA. These tricks yield better ways to detect human errors and ensure model reliability. Or methods to deliver faster results. Today we share six nuggets of wisdom for better FEA.
Why FEA Singularities Are Acceptable 1.0 Introduction You stare in dread at the FEA results, which show unbelievable stresses in small spots at the corners. Don’t panic; they are only stress singularities. Small regions where the FEA predictions are completely wrong...
FEA Errors from Mesh Size 1.0 Introduction When was the last time you actually tested your finite element analysis (FEA) results? Are you sure that every FEA analysis ever ordered is accurate? Will you trust your life to it? In truth, FEA results can be...
