    Abstract

    Material parameters which are dependent on direction of orientation can be best represented by tensors of appropriate ranks. Using tensor transformation rule and associated scalar invariants of the tensor, experimental data can be averaged and reduced to compact constants for engineering documentation and retrieval. Examples on data averaging of composite swelling coefficients and elastic compliances illustrate the simplicity and viability of this tensor averaging methodology.
