Model for Hybrid Composite
نویسنده
چکیده
A micromechanical analysis of the unit cell of a unidirectional hybrid composite is performed using finite element method. The fibers are assumed to be circular and packed in a hexagonal array. The effects of volume fractions of the two different fibers used and also their relative locations within the unit cell are studied. The failure envelopes of the hybrid composites are developed from the micro-stresses within the unit cell for various macro-stress states using the Direct Micromechanics Method (DMM). From the DMM results various phenomenological failure criteria such as maximum stress, maximum strain and Tsai-Hill theories are developed for the hybrid composites. The results for hybrid composites are compared with single fiber composites. _____________ Sayan Banerjee, Graduate Student ([email protected]) B. V.
