Model:
Area, A = 0.01.
Material:
Linear elastic, Young's modulus = 30.0 × 106, Poisson's ratio = 0.3.
Loading and boundary conditions for Step 1:
0.0 at 
0, 
0.0 at 10; displacement boundary conditions applied at the end nodes: 
0.01 + 0.01x.
Loading and boundary conditions for Step 2:
The node at 0 is fixed; 
0 at 10; concentrated load at the free end: 
3000.
Loading and boundary conditions for Step 3:
0.0 at 0, 0.0 at 10; displacement boundary conditions applied at the end nodes: 
0.01 + 0.01x, where x is the value of the coordinates in the undeformed geometry.
Loading and boundary conditions for Abaqus/Explicit:
The node at 0 is fixed; 0 at 10; concentrated load at the free end: 3000 using a smooth step amplitude definition. Solution is computed at time 1.0, including geometric nonlinearity.
All elements yield exact solutions except the cubic beams, which differ from the analytical solution by about 2% for the NLGEOM step and the subsequent perturbation step. The elements are recommended only for linear analysis. The results for pipe elements in Abaqus/Explicit are the same as those in Abaqus/Standard.
