ABSTRACT:
An elastic modulus of an element of a material including fibers in a selected direction is determined as follows. First, a parallel elastic modulus, an orthogonal elastic modulus and fiber orientation of the material are stored. The elastic modulus of the element is determined based on the first elastic modulus, the second elastic modulus and an angle between the fiber orientation of the element and the selected direction such that the elastic modulus is determined as a function of the angle between the fiber orientation of the element and the selected direction when the selected direction is neither parallel nor orthogonal to the fiber orientation of the element.
