Truss Nonlinear Elastic Function

Function

This feature generates a function that reflects the Nonlinear Elastic model from Structural Material to Truss elements.  The Nonlinear elastic behavior of truss elements is defined by a multi-linear stress-strain diagram.

Call

Model > Truss Nonlinear Elastic Function

<Truss Nonlinear Elastic Function>

Name

Saves the name of the function.
 

Total Strain

Saves deformation rate of Truss element.
 

Stress

Saves stress values of Truss elements.
 

Scale Value

Enter a scale factor which will be multiplied by the original function value.

Note: The structure of attributes, properties and materials in GTS requires that the user assigns a Structural Material for all trusses even if in the case of non-linear elastic truss all necessary parameters should have been entered in the Property dialog. In the ‘Add/Modify Structural Material’ dialog select model type ‘Elastic’ and enter an arbitrary Young’s modulus (these settings will not be used in the calculation).

Example

1) Select Model > Property > Material and select Add > Structure.

2) Select ‘von Mises’ for Model Type.

3) Input Yield Stress.
