In the work, these constants are determined for a composite reinforced with cylindrical fibers with a rectangular packing. The obtained results are applied for the calculation of these constants for a composite used in engineering applications. https://jcamech.ut.ac.ir/article_97627_dec87fcd0c647e5942f4760f523ba827.pdf
