Quadratic Elements at finite deformation - Abaqus

[hempres]

Hi all,

Abaqus documentation says:
When large strain gradients or strain discontinuities are expected in the solution—such as in plasticity analysis at large strains, limit load analysis, or analysis of severely loaded rubber components—the first-order elements are usually recommended.

Has somebody an explanation for this?

Thx

I suppose that due to their integration scheme, first order elements are likely more robust and therefore easier to use.
