Abstract
The tensile behavior of two-phase alloy containing a fiber was studied by the finite element method. This problem was carried out on the aluminium matrix with an elastic fiber whose Young’s modulus was 37000 kg/mm2, and was treated as the case of a two-dimensional plane stress model. The results of this simulation were as follows:
(1) The relation between the stress-strain curve and the development of the yielded zone of this two-phase alloy was obtained.
(2) It was found that the tensile stress in the second phase and the shear stress along the interface were affected remarkably by mechanical properties of the matrix and the second phase, particularly by the Young’s modulus ratio.
(3) A new approximate equation was proposed in consideration of the principal stress axis of this two-phase alloy, and this equation was in good agreement with the results calculated by means of the finite element method.
