1. A tension load fixture for applying tension or loading forces to a specimen, the tension load fixture comprising:
a pair of tension arms configured to releasably couple to opposite end regions of a specimen and to apply tension or loading forces to the specimen, wherein the specimen is configured to be positioned between the pair of tension arms and defines a notch between the opposite end regions of the specimen, wherein the notch extends from a side of the specimen to a middle region of the specimen;
an imaging device configured to capture one or more images of the middle region of the specimen, and that is configured to rotate about an axis to facilitate generation of a three-dimensional image of the middle region of the specimen as the specimen is subjected to tension or loading forces; and
a controller communicatively coupled to the imaging device and to a load generator, the controller configured to:
control, via the load generator, application of tension or loading forces to the specimen;
determine, based on the one or more images, dimensions of a plurality of cracks that develop beneath a surface of the specimen and determine specific layers associated with the plurality of cracks in response to the application of tension or loading forces to the specimen, wherein:
the plurality of cracks are different from the notch, and
the dimensions of a crack, of the plurality of cracks, comprise a length of the crack, a height of the crack, and a position of the crack;
track a damage mode, for each specific layer associated with the plurality of cracks, wherein, for each specific layer, the damage mode indicates a matrix crack or a fiber crack; and
output data for each specific layer associated with the plurality of cracks, wherein the data indicates the dimensions of the plurality of cracks and the corresponding damage mode.
