GetMPOrthotropic

GetMPOrthotropic

Syntax

SapObject.SapModel.PropMaterial.GetMPOrthotropic

VB6 Procedure

Function GetMPOrthotropic(ByVal Name As String, ByRef e As Double, ByRef u As Double, ByRef a As Double, ByRef g As Double, Optional ByVal Temp As Double = 0) As Long

Parameters

Name

The name of an existing material property.

e

This is an array that includes the modulus of elasticity.

e(0) = E1 [F/L
2
]

e(1) = E2 [F/L
2
]

e(2) = E3 [F/L
2
]

u

This is an array that includes poissons ratio.

u(0) = U12

u(1) = U13

u(2) = U23

a

This is an array that includes the thermal coefficient.

a(0) = A1 [1/T]

a(1) = A2 [1/T]

a(2) = A3 [1/T]

g

This is an array that includes the shear modulus.

g(0) = G12 [F/L
2
]

g(1) = G13 [F/L
2
]

g(2) = G23 [F/L
2
]

Temp

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.

This item is the temperature at which the specified data is to be retrieved. The temperature must have been defined previously for the material.

Remarks

This function retrieves the mechanical properties for a material with an orthotropic directional symmetry type.

The function returns zero if the data is successfully retrieved; otherwise it returns a nonzero value. The function returns an error if the symmetry type of the specified material is not orthotropic.
