Thermal Loads in Structural Design

If you have a thermal load in structural design, the standard practice is to reduce the values of material properties.

Web under local loads – Nonlinear FEA

The more complex a problem is, and the higher the accuracy needed, the more it makes sense to employ Nonlinear FEA. Will it make sense to use it in solving local web loads? Let’s find out!

How to Tackle Nonlinear Finite Element Analysis

While many FEA packages have a “switch” that literally turns nonlinearities “on” this is not enough! You also need to understand what you wish to do. Learn about it here!

Difference Between Implicit vs Explicit Analysis

Implicit and Explicit analysis differ in the approach to time incrementation. Let's compare them!

Difference between linear and nonlinear elastic material

Both linear and nonlinear elastic materials will elastically return to an “unloaded” state after loading, but the relationship between stress and strain is different in them. Take a look at details here!

Angus Ramsay on Enterfea:
Large Thermal Strains in FEA

If I don't know how something in FEA works... I will ask Angus Ramsay! And I managed to convinced him to share his awesome knowledge with us here about large thermal strains and some other cool things!

Nonlinear geometry benchmark

There are of course benchmarks for a lot of problems. Today I will discuss one for geometric nonlinearity in shells. If you are working with shells or learning nonlinear geometry this is a must read!

Plasticity, isotropic/kinematic hardening… and Boris!

I love how "exotic" isotropic and kinematic hardening sounds! And this time, thanks to Boris you can learn a LOT about this topic - definitely give it a read!

How to approach a snap-through problem

I will discuss various approaches to snap through problems with nonlinear FEA analysis. Understanding this was a stepping stone in my career so I suspect that you may also want to give this a look!
