Anisotropic Elastic Constants of a Fiber-Reinforced Boron-Aluminum Composite

Datta, S. K. / Ledbetter, H. M.

Abstract Elastic constants, both the Cij’s and the Sij’s, were measured and calculated for a laminated, uniaxially fiber-reinforced boron-aluminum composite. Three theoretical models were considered: square-array, hexagonal-array, and random-distribution. By combining several existing theoretical studies on randomly distributed fibers, a full set of elastic constants can be predicted for this model. The random-distribution model agrees best with observation, especially for off-diagonal elastic constants. Considering all nine elastic constants, observation and theory differ on the average by six percent.
