Factor of Safety: Formula, Typical Values, and How to Choose One
What factor of safety means, how to calculate it from yield or ultimate strength, margin of safety, the values codes require, and how to choose one.
Von Mises Stress: What It Is and How to Use It
What von Mises stress means, the formula for 3D and plane stress, a worked example with a safety factor, and when an FEA von Mises plot can mislead you.
Predicting Mechanical Failure with FEA: A Worked Example
How FEA predicts mechanical failure: the failure modes it covers, a worked bracket example with hand-check and safety factor, and the mistakes to avoid.
What Is Fatigue Failure? Causes, Stages, and How to Prevent It
The Short Answer Fatigue failure is the cracking and eventual breaking of a part under loads that are repeated many […]
FEA vs CFD: What’s the Difference and Which One Do You Need?
FEA tells you whether a part will bend or break. CFD tells you how air or liquid moves around it. Here is how to know which one your design needs.
What Is Finite Element Analysis (FEA)? A Practical Guide
Finite element analysis explained in plain language: how FEA works step by step, the main types of analysis, how to read the results, and its limits.
Design Optimization — Reducing Weight or Material Cost Without Sacrificing Strength
Most first-pass designs carry more material than they actually need — optimization is where that extra weight comes off.
Fatigue Analysis: How to Predict How Long a Part Will Last
How fatigue analysis predicts the life of a part under repeated loads: the three methods, the steps from load history to safety factor, and the mistakes to avoid
Motion & Kinematic Simulation — Verifying Moving Assemblies Behave as Intended
A mechanism that looks correct in a static CAD model can still bind, collide, or jam the moment it actually moves.
