A method of making and using a material model utilizes summation, integration or alteration of force, stress, energy or sets of flux vectors that vary across or emanate from three dimensional elements with planar faces. The method receives input from a user to set up one or more three dimensional elements without further division, addition, merging or distortion. Processor steps detect and compute limits of integration across a face nearest a sampling point in coordinate systems local to the face and local to a plane of rotation for any rotation within a material matrix. Patterns of force, stress, energy or sets of flux vectors from a model can be utilized to promote electrical conduction not facilitated by a traditional voltage, detection of properties of an incoming wave, resistance against fracture, or selective separation of material. |

1. A method steps to be performed on or by means of a computing device comprising a processor and memory, with the steps comprising:
(a) receiving from a user information comprising presence or absence of bundling and how many elements or bundles, wherein said elements are three dimensional, enclosed by planar faces, and are parts of a model of a monolithic micro structure; (b) in accordance with step (a), receiving from a user information further comprising whether or not a plurality of unbundled elements all have the same shape, size, and orientation, whether or not a plurality of bundles will all have the same number of elements and orientation, and whether or not a plurality of bundles will all have elements of the same size and shape; (c) in accordance with steps (a) and (b), receiving from a user for each element information further comprising symmetry, presence or absence of tapering, and presence or absence of pyramidal endcaps; (d) in accordance with steps (a) through (c), receiving from a user information further comprising width, depth, length, orientation, spacing, interior angles, height of pyramidal endcaps, a position of a pivot point on each element or bundle, orientation of a rotation axis at said pivot point, magnitude of rotation about said rotation axis, and an amount of tapering further comprising an area of one end face that is a percentage of the area of the other end face; (e) for each face of each element, in a coordinate system comprising an axis perpendicular to a plane containing the face, and comprising another axis in said plane of the face and perpendicular to a rotation axis of the element containing the face, checking values of abscissas and ordinates of vertices to determine which values are upper and lower limits of integration, and which values connect upper edges, lower edges, or both as limits of integration; (f) across one or more faces or within a radius about a sampling point, performing any one or more of a summation, difference, integration, computation and alteration of any one or more of scalars, components of a tensor of order of one or more, components of a rotational displacement, and functions of one or more variables; (g) comparing values from step (f) at one or more sampling points with desired values of a physical quantity, wherein said desired values are calculated with any one or more of scalars, components of a tensor of order of one or more and functions of one or more variables; (h) in accordance with steps (a) through (g), altering any of one or more of shape, orientation and spacing of one or more elements until a model yields said desired values of one or more physical quantities at one or more sampling points. |
