Syntax

SapObject.SapModel.PropMaterial.GetOSteel

VB6 Procedure

Function GetOSteel(ByVal Name As String, ByRef Fy As Double, ByRef Fu As Double, ByRef eFy As Double, ByRef eFu As Double, ByRef SSType As Long, ByRef SSHysType As Long, ByRef StrainAtHardening As Double, ByRef StrainAtMaxStress As Double, ByRef StrainAtRupture As Double, Optional ByVal Temp As Double = 0) As Long

Parameters

Name

The name of an existing steel material property.

Fy

The minimum yield stress. [F/L
2
]

Fu

The minimum tensile stress. [F/L
2
]

eFy

The expected yield stress. [F/L
2
]

eFu

The expected tensile stress. [F/L
2
]

SSType

This is 0 or 1. indicating the stress-strain curve type.

0 = User defined

1 = Parametric - Simple

SSHysType

This is 0, 1 or 2, indicating the stress-strain hysteresis type.

0 = Elastic

1 = Kinematic

2 = Takeda

StrainAtHardening

This item applies only to parametric stress-strain curves. It is the strain at the onset of strain hardening.

StrainAtMaxStress

This item applies only to parametric stress-strain curves. It is the strain at maximum stress.

StrainAtRupture

This item applies only to parametric stress-strain curves. It is the strain at rupture.

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 other material property data for steel materials.

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