Elastic-No Tension (ENT)

Description

The ENT (Elastic-No Tension) material is a one-dimensional constitutive model of linear stress-strain response in compression with zero stress in tension. The ENT model can be used anywhere a UniaxialMaterial object is expected in OpenSees. The ENT model is suitable for concrete stress-strain response in fiber sections. In addition, the model can simulate simple bridge abutment response in a zero-length element.

Syntax

ops.uniaxialMaterial('ENT',tag,E)

Parameters

• tag : integer Unique material identifier
• E : float Elastic modulus in compression

Optional Parameters

None

Notes

• This model is sometimes referred to as Concrete00

Examples

# Modulus of 3600 in compression
ops.uniaxialMaterial('ENT',1,3600)
