Abaqus creep material properties

The following tables provide information about the options you should use to define the various creep laws supported by Abaqus. These options are available on the Creep page in the Materials dialog box.

For detailed information about defining creep material properties, see your solver documentation.

Creep law TIME

Equivalent Creep Strain Rate = A * (EquivalentDeviatoricStress ^n) * (time^m)

Type	Coefficients	Notes
Time Hardening (Norton-Bailey) Power Law	Enter the A, n, and m coefficients in the dialog box.	This combination of inputs corresponds to the *CREEP keyword with LAW=TIME.

Creep law STRAIN

Equivalent Creep Strain Rate = {A * (EquivalentDeviatoricStress^n) * [(m + 1) * EquivalentCreepStrain]^m }^1/(m+1)

Type	Coefficients	Notes
Strain Hardening Power Law	Enter the A, n, and m coefficients in the dialog box.	This combination of inputs corresponds to the *CREEP keyword with LAW=STRAIN.

Creep law HYPERB

Equivalent Creep Strain Rate = e * [sinh (f * EquivalentDeviatoricStress)]^g exp^[-∆H/(R(T-To))]

Type	Coefficients	Notes
O.R.N.L viscoplastic material	C1 = ignoredC2 = ignoredCoefficients a, b, c, and d are ignored.The e, f, and g coefficients in the dialog box correspond to the following terms in the Abaqus equation:e = Af = Bg = n	This combination of inputs corresponds to the CREEP keyword with LAW=HYPERB.Reference Temperature corresponds to the θ^Z term in the Abaqus equation.Temperature Dependent Term corresponds to exp^[-∆H/(RTo)]
