Syntax

public interface IManderConfinedStressStrainCurve : IStressStrainCurve

Remarks

Mander curve is commonly used for concrete materials.

Properties

ConfinedStrength

The confined strength of the material.

Declaration

Pressure ConfinedStrength { get; }

Property Value

Type	Description
OasysUnits.Pressure

InitialModulus

The initial gradient of the stress-strain curve.

Declaration

Pressure InitialModulus { get; }

Property Value

Type	Description
OasysUnits.Pressure

UnconfinedStrength

The unconfined strength of the material.

Declaration

Pressure UnconfinedStrength { get; }

Property Value

Type	Description
OasysUnits.Pressure

Methods

Create(Pressure, Pressure, Pressure, Strain)

Creates a new IManderConfinedStressStrainCurve.

Declaration

static IManderConfinedStressStrainCurve Create(Pressure unconfinedStrength, Pressure confinedStrength, Pressure initialModulus, Strain failureStrain)

Parameters

Type	Name	Description
OasysUnits.Pressure	unconfinedStrength	The unconfined strength of the material.
OasysUnits.Pressure	confinedStrength	The confined strength of the material.
OasysUnits.Pressure	initialModulus	The initial gradient of the stress-strain curve.
OasysUnits.Strain	failureStrain	The strain beyond which the material fails.

Returns

Type	Description
IManderConfinedStressStrainCurve

Remarks

Peak strain is calculated from unconfined strength, confined strength and initial modulus.

Exceptions

Type	Condition
System.ArgumentException	When the peak strain is larger than the failure strain.
System.ArgumentException	When the initial gradient is not a poitive finite value.
System.ArgumentException	When the confined strength is smaller than the unconfined strength.
System.ArgumentException	When the failure strain is smaller than the calculated peak strain.
