cPropMaterialSetMPOrthotropic Method

Sets the material directional symmetry type to orthotropic, and assigns the orthotropic mechanical properties.

Namespace:  ETABS2016
Assembly:  ETABS2016 (in ETABS2016.dll) Version: 16.0.0.0 (16.0.0.0)
Syntax
Copy
int SetMPOrthotropic(
	string Name,
	ref double[] E,
	ref double[] U,
	ref double[] A,
	ref double[] G,
	double Temp = 0
)

Parameters

Name
Type: SystemString
The name of an existing material property.
E
Type: SystemDouble
U
Type: SystemDouble
A
Type: SystemDouble
G
Type: SystemDouble
Temp (Optional)
Type: SystemDouble
The temperature at which the specified data applies. The temperature must have been defined previously for the material.

This item applies only if the specified material has properties that are temperature dependent. That is, it applies only if properties are specified for the material at more than one temperature.

Return Value

Type: Int32
Returns zero if the data is successfully assigned; otherwise it returns a nonzero value.
