Do you need to know math behind FEA?

Recently I asked a lot of my subscribers what they think is the most difficult thing in FEA. While "interpreting results" or "too much theory in materials" appeared quite often, I also got several answers like: My biggest obstacle is actually understanding the mathematical concept behind it. Although I am really interested in the application [...]

Finite Element Analysis workflow

When I first started working with Finite Element Analysis (FEA) I had a huge problem in understanding what to do. I had a basic engineering knowledge but I simply did not understand what was the order of the steps. Suddenly the software had many "modules" and each was screaming at me that some data is [...]

Linear vs nonlinear buckling explained!

By |January 24th, 2017|• Linear Analysis, • Nonlinear Analysis, FEA: Intermediate, FEA Topics:, • Linear Buckling, FEMAP|

Choosing between linear buckling and nonlinear buckling in given case can be difficult. Both approaches have positive and negative aspects. I explain here what are the differences, and when to use each analysis. I promise not to use complicated mathematics, nor highly theoretical approach. Instead, I will use a simple example to easily describe differences. [...]

Linear buckling in plain language!

By |January 2nd, 2017|FEA: Basics, • Linear Analysis, • Stability, FEA: Intermediate, FEA Topics:, • Linear Buckling, Structural Design Topics:|

Buckling is a dangerous phenomenon. It can lead to catastrophic failure of a structure, even if stresses are far smaller than yield limit. You can use linear buckling analysis to verify structural stability. In this post, I will discuss positive aspects and limitations of linear buckling. […]

Linear vs Nonlinear Buckling

By |May 8th, 2016|• Linear Analysis, • Nonlinear Analysis, FEA: Intermediate, FEA Topics:, • Linear Buckling, FEMAP|

Topic of linear and nonlinear buckling is one of the most searched FEA topics. It is understandable, since lack of knowledge about the difference in both approaches can lead to great overestimation of model capacity and following real-life instability failure. In this post I will discuss the difference with a shell example. […]
