The current best-estimates for the dimensions of various test articles is here, along with the relevant experimental parameters and reported forces. Note that complete dimensions are not known in most cases, and some had to be determined via indirect methods (e.g., estimation from photographs).

Credit to Dr. Rodal and others for the great effort in compiling these. Please note some caveats for this data, at that link.
