Beam 3-point bending (Inputs Preparation)
The following table summaries the random variables that have been used for simulation analysis:
|| Standard deviation|
| Young's modulus (E)
||210,000 (MPa)||10,000 (MPa)|
| Point force (f)
||10 (N)||1.4 (N)|
| Height of the beam (h)
||5 (mm)||0.577 (mm)|
| Width of the beam (w)
Creation of the Random Variables
The three Random variables described in previous section are created. Random variables are the inputs of analysis considering uncertainties (reliability, simulation, etc).
Creation of a Parameter
The width of the beam is modelled using a Parameter. Parameters are the input of simulations without considering uncertainties (optimization, etc). Parameters can also be used for values that may need to be changed easily within COSSAN-X.
Creation of a Function
The inertia moment will be expressed using a Function, which depends on the height and width of the beam. In the function definition tab, the name of the objects to used has to be placed between the identifiers <& and &>. Thus the inertia moment of the beam is defined using the following formula:
