Mohr’s circle for plane stress shows the relationship between the state of stress, principal stresses, and maximum shear stress. This article will cover the basics of Mohr’s circle in plane stress, and how it is easily created using MEboost. MEboost also handles bodies under plane strain. To learn about this scenario, refer to the article …
Traditional engineering design employs the concept of a safety factor to prevent failure. In this article we are going to discuss, with a simple example, how probabilistic design can be used as an alternative to safety factors. Background on Safety Factors In engineering design, uncertainties in material strength, material dimensions, and loading is often accounted …
Tolerance analysis is an important part of mechanical design. It has an impact on cost, performance, and quality which requires a requisite amount of study to ensure tolerances result in a successful design that can be effectively manufactured. In this article we will look at tolerance analysis methods, and their pros and cons. We will …
Monte Carlo simulation can be used for tolerance analysis (Monte Carlo tolerance analysis) to determine the rejection rate of assemblies. In this application we will look at an example assembly where parts A and B must fit inside part C with a clearance fit. For performance reasons we want to minimize the total clearance so …
