4.3.1 Unconstrained Continuous Fiber Distribution

The material type for an unconstrained continuous fiber distribution material is “continuous fiber distribution”. The following parameters must be defined:
<fibers> Specification of the fiber material response
<distribution> Specification of the fiber density distribution
<scheme> Numerical integration scheme
The <fibers> tag encloses a description of the fiber constitutive relation and associated material properties, as may be selected from the list provided in Section 4.2.1↑. The <distribution> tag encloses a description of the fiber density distribution function, as may be selected from the list presented in Section 4.3.3↓. The <scheme> tag specifies the numerical integration scheme, as may be selected from the list presented in Section 4.3.4↓.
Example:
<material id="1" name="Material" type="solid mixture">
  <solid type="neo-Hookean">
    <density>1</density>
    <E>1</E>
    <v>0.3</v>
  </solid>
  <solid type="continuous fiber distribution">
    <fibers type="fiber-exponential-power-law">
      <alpha>0</alpha>
      <beta>2</beta>
      <ksi>1</ksi>
    </fibers>
    <distribution type="spherical">
    </distribution>
    <scheme type="fibers-3d-gkt">
      <nph>7</nph>
      <nth>11</nth>
    </scheme>
  </solid>
</material>
