Motovated > Engineering Tips and Tricks Engineering Tips and Tricks Engineering Design Tips A handy rule of thumb for quickly estimating the strength of engineering sections without calculation. Hints for designing thin plastic sections as to act as a living plastic hinge for plastic products. The importance of considering tooling when designing machined parts to save money in the machine shop. With clever design Inflection Points can be utilized in components to lower stress around welds. A comparison of cross bracing designs under torsional loading conditions. A rule for designing effective folded sheet metal designs for ease of fabrication. Have you got a difficult bolted joint? See why increasing the pre-load on bolts may allow them to live. Adding formed features to sheet metal parts can improve the strength and aesthetic appeal of a design. Engineering Analysis Tips An explaination of inplane and large displacement tools using an example flat-walled tank analysis. A comparison of a simple example with and without inplane effects. Check contact stresses by using the Hertzian Contact Equation and maximise machine life. See why a bigger weld is not always stronger and can have higher manufacturing costs in the long run. Maximise life under Impact Loading while minimizing material used based on energy absorbsion. This hint shows how FEA can be used to Optimize the Design of a Bracket to reduce manufacturing cost. This tip relates to analysis of re-entrant stresses in Finite Element Analysis (FEA). ←Back to Links
