Anisotropic shrinkage

    Table of contents
    No headers

    Shrinkage that has different magnitudes in different directions.

    Anisotropic shrinkage occurs in filled materials due to the restriction of shrinkage along the fiber length, which tends to be in the flow direction. This type of shrinkage also occurs in unfilled materials when the molecules have insufficient time to relax from the viscous elongation due to shear during flow.
