🧭 CAE Compass Edition # 26 Imagine you're having a great day. The sun is shining, you’re feeling flexible and happy, ready to take on whatever life throws at you. But suddenly, the temperature drops, and you turn stiff. Sounds dramatic, right? Well, this is exactly what happened to the infamous ship and the root cause was found 40 years later! And still, she doesn't know the root cause 😑 Like people, materials also behave differently depending on the temperature. At room temperature, steel is...

🧭 CAE Compass Edition # 24 In the previous edition, we explored what are composite materials and their applications. This time we will look at the basic structure of composites, how they are modeled in CAE and some resources for further learning. Let’s go back to the definition! A composite material is simply two different materials combined to make something better. When you mix them, you get a material that’s extra strong, super light and even resistant to electricity! They’re used instead...

🧭 CAE Compass Edition #19 Imagine you're at a dance party. Some people are busting out crazy moves, twisting, turning, and jumping all over the place. Others are just swaying side to side or maybe doing a little shuffle. Now, think of each dancer as a point in a structure you’re analyzing with Finite Element Analysis. The dance moves they can perform represent their "degrees of freedom" (DOF). In this edition of CAE Compass, we will break down the concept of Degrees of Freedom (DoF) in a...

🧭 CAE Compass Edition #18 I know it’s been ages since our last chat, but fear not – it is my responsibility to sprinkle CAE wisdom your way at least once a month, no matter how busy my schedule gets! Welcome to the 18th edition of the CAE Compass newsletter! In today's edition, I'll take you through a crucial topic: Nonlinear Material Models. When we talk about materials and how they react to forces, we often think about simple stretching or bending. But some materials behave in more complex...

🧭 CAE Compass Edition #17 Do you think Modal analysis is limited to finding the natural frequencies of a body/assembly alone? Well, this edition is going to change your mind! There's no doubt that, Modal analysis is used across industries like aerospace, automotive, civil engineering, manufacturing & what not. While some might believe it's solely about identifying those resonant frequencies (as taught in schools), the truth is, it's a versatile tool with a lot more to offer. Don't believe...

🧭 CAE Compass Edition #15 If you've ever faced CAE interviews, chances are you've encountered questions like: Why is Von-Mises Stress preferred the most during FEA calculations? What’s so special about it? or why not judge the results based on other Stresses (like Normal or Max Principle)? The answer to these questions depends on many factors, but I’ll try to break it down into simple steps so that you can ace the interviews with a precise explanation. When you don't know any of the answers...

🧭 CAE Compass Edition #14 How can we simulate the deformation of a car during a collision, accounting for the rapid changes in forces? Hey Buddy! Welcome to the special edition of CAE Compass where we will explore Nonlinear Explicit Dynamic Analysis. Don't worry about the complex terminology, we're going to break it down into straightforward terms. Let's first begin with Dynamic analysis. Dynamic analysis involves studying how structures respond over time when subjected to forces, impacts or...
