Fiber Orientation analysis results

    This help topic specifies the results for a Fill analysis or Fill+Pack analysis sequence on a thermoplastic material with fiber or filler content.

    Text based results

    The following table lists the text results generated by using the fiber option in a Fill analysis or Fill+Pack analysis sequence.

    Graphical results

    The following table lists the graphical text results generated by using a material with fiber or filler content in a Fill analysis or Fill+Pack analysis sequence, and indicates whether each result is supported for the following analysis technologies:

    • Midplane
    • Dual Domain
    • 3D

    For more information about a result, including how to interpret the display, click on the result name.

    9 Fiber breakage analysis results are produced only when the option to Calculate fiber breakage is enabled in the Fiber Solver Parameters.

    Topics in this section

    • Average fiber orientation result

      The Average fiber orientation result is generated by a Fill or Fill+Pack analysis using Midplane or Dual Domain analysis technology, when the option to perform Fiber orientation analysis if fiber material is enabled.

    • Fiber orientation tensor result

      The Fiber orientation tensor result shows the orientation tensor (degree of orientation) at the end of the injection molding process.

    • Linear thermal expansion coefficient results

      The Linear thermal expansion coefficient result indicate any shrinkage that has occurred in relation to temperature changes.

    • Poisson’s ratio (fiber) result

      The Poisson’s ratio (fiber) result is a fiber-over-thickness (FOT) averaged value, therefore, it is an element-based value averaged over all the laminates of each element.

    • Poisson’s ratio (v12) result

      The Poisson’s ratio (v12) result indicates the strain in the second principal direction caused by the stress in the first principal direction.

    • Poisson’s ratio (v13) (3D fiber) result

      The Poisson’s ratio (v13) result is generated from a Fiber orientation Pack analysis using 3D analysis technology.

    • Poisson’s ratio (v23) (3D fiber) result

      The Poisson’s ratio (v23) result indicates the strain in the third principal direction caused by the stress in the second principal direction.

    • Shear modulus (fiber) result

      The Shear modulus, sometimes called the rigidity modulus, refers to the change produced by a tangential stress, and provides a measure of how stiff the material is.

    • Shear modulus (G12) result

      The Shear modulus (G12) result shows the shear strain applied in the XY direction, coinciding with the fiber orientation direction.

    • Shear modulus (G13) (3D fiber) result

      The shear modulus, sometimes called the rigidity modulus, refers to the change produced by a tangential stress, and provides a measure of how stiff the material is.

    • Shear modulus (G23) (3D fiber) result

      The Shear modulus (G23) result indicates the shear strain applied in the YZ direction (second and third principal directions).

    • Tensile modulus, principal direction results

      The Tensile modulus, principle direction results indicate how much stress is needed to cause a unit of movement.
