There are two kinds of people. Those who know FEM and those who truly understand it. My colleague Ajay Taneja falls in the second category. He is constantly striving to understand it more intuitively.
Over the past couple of years, Ajay has become my go to guy for anything related to FEM. He has a real knack to explains these things in an intuitive, simple way.
Got a glimpse of this exceptional ability again in the recent ‘under the hood’ lectures that Ajay is giving at office.
Fortunately for us, Ajay doesn’t keep his knowledge confined and he has been sharing his discovered insights and understandings via blog posts, so here’s the list of blog posts that I will highly recommend to people who truly want to understand FEM, all penned by Ajay.
- On Engineering Strain and True Strain
- On the physical interpretation of carrying out integration by parts in Galerkin’s WRM for FEA
- On the vibration analysis of MDOF systems
- Eigen Values:Physical interpretation
- Von Mises Stresses
- On the problematic finite element behaviour
- On the phenomenon of necking
- On isotropic and kinematic hardening
- Understanding the Bauschinger effect
- On the shape functions and their requirements
- On the physical interpretation of Galerkin’s weighted residual statement
- Lateral ties in reinforced concrete columns and their state of stress
- Stress, principal stress and stress invariants
- On Eigen values and eigen vectors
- On the difference between types of finite element analysis
- Higher the modes faster the frequencies
Over to you.
Don’t forget to thank Ajay.
