We propose an evaluation method for macroscopic elastic constants of composites, which is called the effective-mean-field method. The method is based on Mori–Tanaka’s mean-field (MTMF), and the effective-medium approximation methods, in which complex elastic fields disturbed by many inclusions are replaced by the average fields of a virtually homogenized composite, and the MTMF formulae are utilized in the entire fraction range of inclusion. It is demonstrated for porous samples that the proposed method can reproduce power-law behavior with regard to porosity.

    The spatial structure of the correlation function of the order parameter of the $$ d_{x^2 - y^2 } $$ symmetry has been investigated within the t- J model in the generalized mean field approximation taking into account the 'no-double occupancy' constraint due to strong electron correlations. A...

    The mass of the neutron star PSR J1614-2230 is calculated in the framework of relativistic mean field theory. In our calculations, we choose nine nucleon coupling constants (i.e. CZ11, DD-MEI, GL85, GL97, NL1, NL2, NLSH, TM1 and TM2), assuming that the neutron star only consists of neutrons,...
