As products become increasingly complex, with downward pressure on overall pricing, this has led to an inevitable increase in the geometric complexity of mechanical components. While this has allowed components to perform multiple functions, it has led to complex load transfers and possible concentrations of stresses. A stress concentration is defined as a high localized stress, compared to the average stress of the body, and is typically found in a region that has an abrupt geometric change. 

Our latest Hardware Guide post will show you how to identify stress concentrations in your designs, and then show you how to reduce stress concentrations using real-world examples to illustrate the concept.

stress concentrations

We go over common issues to avoid for reducing stress concentrations, including:

  • Do not use sharp corners along a load path.
  • Do not make a large size transition between loaded features. The stiffness mismatch will drive the stress concentration much higher.
  • Don’t assume that the same size radius works for all features. Remember that the stress concentration is based on a ratio, not a magnitude.
  • Don’t place a stress concentration in a high cyclic load if you absolutely must use a sharp corner.

By reducing stress concentration in your designs, you should be able to achieve higher load ratings, reliability, and fatigue life. Check out our latest Hardware Guide post to learn more!

Introduction

The rich text element allows you to create and format headings, paragraphs, blockquotes, images, and video all in one place instead of having to add and format them individually. Just double-click and easily create content.

A rich text element can be used with static or dynamic content. For static content, just drop it into any page and begin editing. For dynamic content, add a rich text field to any collection and then connect a rich text element to that field in the settings panel. Voila!

Headings, paragraphs, blockquotes, figures, images, and figure captions can all be styled after a class is added to the rich text element using the "When inside of" nested selector system.
