Interface IManderStressStrainCurve
A type of IStressStrainCurve for an unconfined concrete IMaterial. Refer 'Mander J.B., Priestley M.J.N., and Park R. (1988). "Theoretical Stress-Strain Model for Confined Concrete", ASCE Journal of Structural Engineering, V. 114, No. 8, pp. 1804-1826' for further details.

Syntax
public interface IManderStressStrainCurve : IStressStrainCurveRemarks
Mander curve is commonly used for concrete materials. If the failure strain is less than two times the peak strain, the curve doesn't reach the zero stress point and it ends at the failure strain.
Properties
InitialModulus
The initial gradient of the stress-strain curve.
Declaration
Pressure InitialModulus { get; }Property Value
| Type | Description |
|---|---|
| OasysUnits.Pressure |
PeakPoint
The point of maximum stress.
Declaration
IStressStrainPoint PeakPoint { get; }Property Value
| Type | Description |
|---|---|
| IStressStrainPoint |
Methods
Create(Pressure, IStressStrainPoint, Strain)
Creates a new IManderStressStrainCurve stress-strain curve.
Declaration
static IManderStressStrainCurve Create(Pressure initialModulus, IStressStrainPoint peakPoint, Strain failureStrain)Parameters
| Type | Name | Description |
|---|---|---|
| OasysUnits.Pressure | initialModulus | The initial gradient of the stress-strain curve. |
| IStressStrainPoint | peakPoint | The point of maximum stress. |
| OasysUnits.Strain | failureStrain | The strain beyond which the material fails. |
Returns
| Type | Description |
|---|---|

Exceptions
| Type | Condition |
|---|---|
