● Problem Description ● In this exercise, a cantilever beam is subjected to a static load. The beam

is initially analyzed using small deformation theory. However, after reviewing the results, it becomes apparent that small deformation theory is not appropriate for this problem. Subsequently, a large deformation analysis is performed and its results are compared to the small deformation analysis.

● Problem Description (Cont.) ● The model is made using eight 2D plane stress, assumed strain, reduced

integration (type 114) elements. The elements are uniformly spaced along the length of the beam (i.e. a mesh, eight elements wide and one element deep). The assumed strain, reduced integration element is designed specifically for in-plane bending and is well suited for this problem.

● Objectives: ● Small vs. large displacement analysis ● Linear elastic theory

● Required ● No Supporting file is required.

Suggested Exercise Steps: 1. 2. 3. 4. 5.

Create a new database named tip_load Create a 100 x 2 quad surface cantilever geometry Create 8 x 1 quad mesh elements Convert surfaces to elements Create an isotropic material with Young’s modulus = 3e7, Poisson's ratio = 0.3, and mass density = 0.00074 6. Create a 2D planar geometric property, set thickness = 1 7. Create boundary conditions, fix the left edge in the X and Y directions 8. Create a 6000 lb point load in the negative Y direction and apply to top right node 9. Create a linear static loadcase, # steps = 1 10. Create a plane stress job ● ● ●

Select linear elastic analysis Select assumed strain Select 114 as the element type

11. Submit model for analysis 12. View results by plotting the Y displacement
