Interface IParabolaRectangleStressStrainCurve

A type of IStressStrainCurve which is initially parabolic. The stress is constant beyond the yield point. The material provides no strength beyond the failure point.

Inherited Members

IStressStrainCurve.FailureStrain

IStressStrainCurve.StressAt(Strain)

Namespace: Oasys.AdSec.Materials.StressStrainCurves

Assembly: AdSec_API_IDL.dll

Syntax

public interface IParabolaRectangleStressStrainCurve : IStressStrainCurve

Remarks

Parabola-rectangle curve is commonly used for concrete materials.

Properties

YieldPoint

The point up to which the stress-strain relationship is parabolic, and beyond which there is no change in stress with change in strain.

Declaration

IStressStrainPoint YieldPoint { get; }

Property Value

Type	Description
IStressStrainPoint

Methods

Create(IStressStrainPoint, Strain)

Creates a new IParabolaRectangleStressStrainCurve.

Declaration

static IParabolaRectangleStressStrainCurve Create(IStressStrainPoint yieldPoint, Strain failureStrain)

Parameters

Type	Name	Description
IStressStrainPoint	yieldPoint	The point up to which the stress-strain relationship is parabolic, and beyond which there is no change in stress with change in strain.
OasysUnits.Strain	failureStrain	The strain beyond which the material fails.

Returns

Type	Description
IParabolaRectangleStressStrainCurve

Remarks

The initial gradient of the curve is set such that the parabola has zero gradient at the yield point.

Exceptions

Type	Condition
System.ArgumentException	When the yield strain is larger than the failure strain.
System.ArgumentException	When any of the stress-strain inputs is negative or infinite.
