Hello everyone, 

the task is as follows:

W01C0001-Introduction Beam 1D (not scored)

 

In this section you will create a 1D finite element model (beam) and run a linear static analysis. You will be assessed on your ability to perform the following:

  - create a simple 1D model with beam elements,

  - manage units, various loadings, boundary conditions,

  - explore the main output variables globally and at specific points.

 

Warning: Before answering any of the questions you will be required to create and run a model as described in this introduction. This may take approximately 15 to 25 minutes. Please note that this Introduction page is not scored.

 

Model creation (Carefully read all the information before creating your model):

 

Use consistent units when creating your model.

Note: be aware that some data may be provided with non-consistent units.

 

Locate the origin of the coordinate system (0., 0., 0.) at the left end of the beam. The beam axis is aligned along the X-axis:

  - Length L: 4m

Section properties:

  - Rectangular section

    - h along Y-axis: 0.2m

    - W along Z-axis: 0.1m

Material properties:

  - Young Modulus E: 12000MPa

  - Poisson's ratio Nu: 0.3

  - Density: 0.6gram/cm3

 

No mesh size or element density is imposed.

 

Make sure you respect the following mesh constraints: a concentrated load will be applied at a point located at X=3L/4. Output may be required at X=0, X=L/2, X=3L/4, X=L.

 

Mesh: use Beam elements.

 

Analysis: define a linear static analysis.

 

Loading: the following loads are applied simultaneously to the model:

- a gravity loading

   Y-direction

   gravity acceleration: -10m/s2

- a concentrated force applied at X=3L/4

   Y-direction

   F=-3kN

- a lateral pressure oriented to the +Z-axis

   P=5kPa

Tip: the 'Pressure' loading should be applied as an equivalent 'Line Load'.

 

Boundary conditions: the beam is fully fixed on the left end (X=0) and pinned on the right end (X=L).

 

Output: use the default output options.

Make sure you provide rounded values in your answers.

 

Click on “Continue” before moving to the next question.

the suggested answers  given in the exam are shown in the attached image JPG, 

the problem is when i run the analysis i get none of these suggestions and what i get is 34.75mm, 

i really need  the  help of anyone who is able to do !!!

thanks in advance, 

 

Intisar,
