What is the difference between maximum principal strain and maximum in-plane principal strain?
For the purpose of answering/explaining this, it does not need to be restricted to strains (i.e., it can be stresses too). I am mainly trying to understand when to use which one (i.e., if I am ...

What is the meaning of the traction continuity condition in the generalized momentum balance (continuum mechanics)?
In Nonlinear Finite Elements for Continua and Structures by Belytschko and al. it is stated:
As we have already noted, the strong form, or generalized momentum balance, consists of the momentum ...

Calculating the von mises stress in a 3D beam when given stresses and moments on both ends
I want to calculate the von mises stress in a given structural member. I want to generate a von-mises plot from this data.
The forces are according to the local coordinate system of the beam. Also, I ...

Why do I see stresses on the fixed support face of a solid body in FEA?
Below, I have shared pictures of a simple model in FEA. As it can be seen that the face onto which the fixed support is applied, there exists Von-Mises stresses. I cannot comprehend why. Since the ...

How to perform 3 point bending test by using force instead of displacement in ABAQUS?
I know you can apply displacement to a rigid body (cylindrical rod) to perform a 3 point bending test in ABAQUS. Is it possible to apply force to the rod (e.g. rod with super high young's modulus so ...
