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:
<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 4.2.2↑. 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↓.
Example:
<material id="1" name="Material" type="uncoupled solid mixture"> <solid type="Mooney-Rivlin"> <density>1</density> <c1>1</c1> <c2>0.3</c2> </solid> <solid type="continuous fiber distribution uncoupled"> <fibers type="fiber-exponential-power-law-uncoupled"> <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>
