Example – Cantilever beam

E = 210000N/mm2

n = 0.3L = 100mma = 10mmb = 10mmF = 100N

Objective:Compute the maximum deflection Tasks:Create a table and compare resultswith results obtained from beam theory?Display the deflection figure?Topics:Topics: Start of analysis, Element type,Real constants, Material, modeling, ele-ment size for beam models, saving/restoring

Modeling considerations• As you begin your model generation, you will (consciously or

unconsciously) make a number of decisions that determine how youwill mathematically simulate the physical system:– What are the objectives of your analysis?– Will you model all, or just a portion, of the physical system? – How much detail will you include in your model? – What kinds of elements will you use? How dense should your finite

element mesh be? • In general, you will attempt to balance computational expense (CPU

time, etc.) against precision of results as you answer these questions.

• The decisions you make in the planning stage of your analysis will largely govern the success or failure of your analysis efforts.

Example0100 4

Modeling considerations• Linear or Higher Order Elements• Take Advantage of Symmetry

– The axis of symmetry must coincide with the global Cartesian Y-axis.– Negative nodal X-coordinates are not permitted.– The global Cartesian Y-direction represents the axial direction, the

global Cartesian X-direction represents the radial direction, and the global Cartesian Z-direction corresponds to the circumferential direction.

– Your model should be assembled using appropriate element types: • For axisymmetric models, use applicable 2-D solids with KEYOPT(3) = 1,

and/or axisymmetric shells. In addition, various link, contact, combination, and surface elements can be included in a model that also contains axisymmetric solids or shells. (The program will not realize that these "other" elements are axisymmetric unless axisymmetric solids or shells are present.)

• How Much Detail to Include• Appropriate Mesh Density

• The process for using submodeling is as follows: –– Create and analyze the coarse model.Create and analyze the coarse model.– Create the submodel.– Perform cut boundary interpolation (CBI).– Analyze the submodel.– Verify that the distance between the cut

boundaries and the stress concentration is adequate.
