Nodal vs Element Results
Quick demonstration of how results are calculated and presented in FEA as Element or Nodal This simple model shows how results such as strain and stress are calculated at the centre of an element and then are averaged at nodes by finding the average of all connected elements. The model has 2 plane strain elements,…

Load Cell Investigation
Had a problem last week where a Load Cell broke in half during a high load (around 1MN) fatigue testing sequence. Visual inspections indicates the crack had initiated from a small radii feature in the load cell body and propagated to the screw thread at the centre. Was away over the weekend but I wanted to…

Where to find the best online Finite Element Analysis PDFs
Finite element method pdfs these days are numerous on the internet. Some are of better quality than others and search results often are swamped by generic cut and paste lecture notes. The two references that I have found useful in understanding FEA and that are available for public use are listed below. Finite Element Analysis…

Constant Strain Triangle Elements (CST)
Quickfem currently uses planar constraint strain triangle elements (CST). CST elements are the simplest planar elements to create, solve and understand, and as such are ideally suited to FEA on mobile platforms. The main limitation of CST elements is that they are overly stiff in bending, however, this can be addressed by increasing the number…
