29.52.1 FailureRatios(...)

This method creates a FailureRatios object.

Path
mdb.models[name].materials[name].concrete.FailureRatios
session.odbs[name].materials[name].concrete.FailureRatios

Required argument

table

A sequence of sequences of Floats specifying the items described below.

Optional arguments

temperatureDependency

A Boolean specifying whether the data depend on temperature. The default value is OFF.

dependencies

An Int specifying the number of field variable dependencies. The default value is 0.

Table data

  • Ratio of the ultimate biaxial compressive stress to the uniaxial compressive ultimate stress. The default value is 1.16.

  • Absolute value of the ratio of the uniaxial tensile stress at failure to the uniaxial compressive stress at failure. The default value is 0.09.

  • Ratio of the magnitude of a principal component of plastic strain at ultimate stress in biaxial compression to the plastic strain at ultimate stress in uniaxial compression. The default value is 1.28.

  • Ratio of the tensile principal stress value at shear in plane stress, when the other nonzero principal stress component is at the ultimate compressive stress value, to the tensile cracking stress under uniaxial tension. The default value is 1/3.

  • Temperature, if the data depend on temperature.

  • Value of the first field variable, if the data depend on field variables.

  • Value of the second field variable.

  • Etc.

Return value

A FailureRatios object.

Exceptions

RangeError.
