How should 2x2 twills be modeled in an Abaqus FEM simulation of Lamb waves in a composite plate?

In order to investigate Lamb waves in a carbon-fiber composite plate (size: 0.5m x0.5m), which comprises unidirectional, biaxial and twill layers, I homogenized the 3D properties of each layer....

In Abaqus, is it possible to remove some elements from a sequence obtained by getByBoundingBox() ?

Basically, I tried to do the following: >>> p1 = p.edges.getByBoundingBox(-1,-1,-1,1,1,1) >>> p2 = p.edges.getByBoundingBox(-0.26,-0.26,-1,0.26,0.26,1) >>> pickededges...

When does Abaqus use the Total Lagrangian and when the Updated Lagrangian formulation?

Total and Updated Lagrangian formulations are generally available for both the implicit and nonlinear explicit dynamic analysis. But when is which applied? Does Abaqus mix them?

What changes in Abaqus/Standart(Implicit) when chosing transient/moderate dissipation or quasi-staic?

Abaqus implicit dynamic analysis offers the user 4 choices of application: - default - transient fidelity - quasi-static - moderate dissipation Do these use different implicit integrators or...

How can I increase the precision in an Abaqus explicit dynamic analysis?

How can I get a better resolution so I can better determine where buckling starts? It seems Abaqus automatically determines the number of increments. What does the number of increments depend on?

How can an SS4 boundary condition be implemented on a cylinder in Abaqus?

I am trying to define boundary condition in a cylindrical coordinate system in Abaqus. I have to implement an SS4 boundary condition defined as: 1. displacements: u (axial) = v (circumferential) =...
