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?

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?

Abhimanyu Kumar

it has been well explained in abaqus analysis manual as well as keyword manual (briefly)

Michael A Jandron

As Abhimanyu mentioned - read the manual, but the short answer is yes. They balance a trade-off of accuracy, solution time, and numerical damping. Definitely keep an eye on the energies during the analysis, too.
