Today, Let’s talk about some basics of ductile and brittle materials… and how you can find an appropriate failure criteria for brittle materials with defects! I registered an audio file to make it more easy to understand, I hope this subject will interest you! 1 Rupture criterions for ductile and brittle materials Usually, when we […]

## Safety factor: How do I calculate that?

This article talks explains the concept of safety factor and how it is calculated. It’s a fundamental notion that every mechanical engineer have to understand well. How do I know if the design of my part is « safe » enough? That’s a difficult question that many designers asked themselves. One of the potential answers involves the […]

## What is stress? Explanation with images

Stress Let’s start with something simple. Let’s visualize a pressure applied on an object. The pressure is causing a certain deformation to your object. After I applied the pressure, what is happening inside the object? Let’s assume the object is composed of a lot of smaller cubes. What is actually happening to one of the small […]
