Habituating FEA

We live in a complex, nonlinear world, but what are the sources of nonlinearity in finite element analysis (FEA)? Contact Nonlinearity - ...

A summary of the differences between plane stress, plane strain and axisymmetric elements. Element Plane stress ...

In the FEA vs. FEM article, we distinguished the two by introducing FEM as the numerical foundation of FEA. It is the underlying method tha...

Thick shells are capable of modelling transverse shear deformation whilst thin shells do not. Thick shells are governed by the  Mindlin–Reis...

A comparison of the differences between membrane, plate and shell elements. Element Membrane Plate Shell...

Standard beam theory ( Euler-Bernoulli bending theory) assumes no deformation by shear. This can be safely applied to thin beams that are l...
