| 1 | INSTANTANEOUS THERMAL EXPANSION BEHAVIOR OF HETEROGENEOUS MATERIALS WITH A WORK-HARDENING ELASTOPLASTIC MATRIX AND ELASTIC SPHEROIDAL INHOMOGENEITIES显示文摘The instantaneous thermal expansion behavior of two-phase hetero-geneous materials subjected to a uniform temperature change is explored in the presentstudy.The matrix phase is assumed to be a work-hardening ductile metal and thedispersive phase is assumed to consist of either aligned or randomly-oriented,elastic,spheroidal inhomogeneities.The plastic flow and decreasing stiffness of the matrixduring Eshelby’s transformation strain of the equivalent inclusions are accounted for byusing the deformation theory of plasticity.The explicit results of the instantaneousoverall thermal expansion coefficients and the critical inelastic temperature changes arepresented for aligned disc-and fiber-inclusions.For the spherical and randomly-oriented spheroidal inclusion,the present study demonstrates that when the yielding ofthe composites is governed by the average matrix stress,the overall response is alwayselastic in spite of the temperature change. | ZHANG, QJ NAN, CW YUAN, RZ | 1995 | Acta Mechanica Solida Sinica1995，8，3： | 1 |

| 6 | STUDY ON STRUCTURE,CHEMICAL BOND AND THERMOELECTRIC PROPERTY OF BORON CARBIDES显示文摘The correlation between structure, chemical bond and thermoelectric properties of boron carbides is discussed based on structural calculations with self-consistent-field discrete variation (SCF-DV-Xa) method, one of calculation methods of molecular orbital in quantum chemistry. Nine different structural models for calculation are proposed. The calculated results show that the chain is negatively charged and the icosahedron is positively charged, i.e. [C-B-B(C)]δ-[B11B(C)]δ.
