Analysis and Evaluation of Fiber Orientation Reconstruction Methods

Abstract: The calculation of the fiber orientation of short fiber-reinforced plastics with the Fokker–Planck equation requires a considerable numerical effort, which is practically not feasible for injection molding simulations. Therefore, only the fiber orientation tensors are determined, i.e., by the Folgar–Tucker equation, which requires much less computational effort. However, spatial fiber orientation must be reconstructed from the fiber orientation tensors in advance for structural simulations. In this contributio… Show more

“…In the second step, the stiffness of the composite is composed of the stiffnesses for the individual directions of an ODF using the Voigt approach [28]. For the ODF, the method of maximum entropy [29] is used like for the creation of the RVEs (see Section 2). The neural network method is abbreviated with NN and the two-step homogenization with the Mori-Tanaka Method as MT in the following.…”

“…Therefore, the existing RDI model has been extended to the Arbitrary-Reconsidered-Double-Inclusion (ARDI) model, by using the complex modulus to consider the damping behavior. Afterwards, the orientation distribution function (ODF) has been reconstructed according to the maximum entropy method (MEM) [15] for a number of orientation tensors. This method allows the creation of a discrete ARDI material database.…”

“…For this, the spatial construction of an icosphere has been used. A detailed description can be found in [15]. In the next step, the effective tensors are rotated into a discrete number of directions of the icosphere, according to Equation (6):…”
