ジャーナル フリーA theory developed in Part I has been applied to predict the yield loci in plane loading of unidirectional fiber composites consisting of an elastic-perfectly plastic matrix and elastic fibers. The Levy-von Mises equations are used as the plastic constitutive equations of the matrix. Results are explicitly shown for a boron fiber-aluminum system subjected to biaxial tension and longitudinal tension/longitudinal shear, including the effect of thermal residual stresses. Perfect correspondence of the results with the phenomenological failure criterion proposed by Tsai and Wu is obtained.抄録全体を表示PDF形式でダウンロード (527K) -

ジャーナル フリーTensile tests on a group of single Al-alloy sheet specimens and a group of adhesively bond Al-alloy laminate specimens were carried out. Two points are apparent from the comparison of the tested results ; (1) the breaking stress and Young's mudulus of the laminate specimen obey the simple law of composition, (2) the fracture toughness property of the laminated specimen is improved fairly well by the composition effect. The cause of the second effect is briefly discussed in this paper, as well as the whole test data.抄録全体を表示PDF形式でダウンロード (1855K) -

ジャーナル フリーUnidirectional solidification of eutectic alloys offers a favorable approach for producing metal matrix composites. In this paper, Ni-Ni3Ta eutectic alloys have been unidirectionally solidified over a wide range of growth rate, and the microstructures and the mechanical properties were studied. In this eutectic system, a solubility limit of Ta in Ni (α) phase decreases considerably with temperature, suggesting the possibility of obtaining additional Ni3Ta phase and strength via precipitation processes. Main results obtained here are as follows. (1) The microstructure of unidirectionally solidified Ni-Ni3Ta eutectic alloy consists of roughly parallel platelike Ni3Ta embedded in Ni (α) matrix. Well aligned structure was obtained at the range of solidification rate between 100 mm/hr to 150 mm/hr, and maxima in tensile strength versus solidification rate curve occured in this range. (2) Widmanstätten type Ni3Ta precipitates were produced in Ni (α) matrix after heat treatment, and morphologies of precipitate structures were differed by the heat treatment conditions. Significant strengthening effect was noted in the specimen heat treated at 1, 000°C for 48 hrs. (3) Unidirectionally solidified and heat treated Ni-Ni3Ta eutectic composites exhibited excellent mechanical properties. The tensile strength was 129 kg/mm2 at room temperature and 51 kg/mm2 at 1, 000°C. (4) At room temperature, the unstable fracture of Ni-Ni3Ta eutectic composites was caused by the cleavage of Ni3Ta platelet, whereas at high temperature, the stable fracture of the composites was accompanied with the multiple fracture of the platelets.抄録全体を表示PDF形式でダウンロード (8986K) -

ジャーナル フリーThickness variation of the laminated biased FRR (Fiber Reinforced Rubber) composite plate under axial tension is measured by micrometer. It is found that Poisson's ratio in the thickness direction, νxz, changes its value from positive to negative due to cord angle and takes zero at the angles of 3 and 45 degrees. An approximate formula for νxz is derived through the assumption that the laminate is incompressible. This formula agrees well with the experimental results.抄録全体を表示PDF形式でダウンロード (230K) -
