### 4.3.2 Uncoupled Continuous Fiber Distribution

The material type for an uncoupled continuous fiber distribution material is “continuous fiber distribution uncoupled”. The following parameters must be defined:
 Specification of the fiber material response Specification of the fiber density distribution 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 4.2.2↑. 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↓.
