Problem 1: Deep Beam
In this problem we look at the analysis of a deep beam with a concentrated load in the middle. This problem serves as an introduction to for input and output of a PLANE solid linear elastic model into ABAQUS.

Problem 2: Bernoulli vs. Timoshenko Cantilever Beams
The dimensions of the beam are . The Material properties are: . The concentrated load at the cantilever end is . The effective shear area for the Timoshenko beam is . Note that in some texts, the inverse of this relationship is given . The exact solution for the vertical displacement at the cantilever end for the Bernoulli beam is given by:
While that for the Timoshenko beam is given by:

Problem 4: Elasto-Plastic Buckling of a Plate
A plate that is thick and wide is loaded until it buckles around the minor axis. The problem will be considered as a plane problem. The Euler buckling load can be calculated as follows:
The critical load per width of the plate is given by:
The relationship between the true stress and the plastic strain is given by:
True Stress(MPa) | Plastic Strain |

800 | 0 |
900 | 0.1% |
1000 | 0.3% |
1100 | 0.7% |
