【摘要】 研究了无穷大各向同性基体中完善粘结的球向各向异性球夹杂,发现当基体在无穷远受均匀荷载时,球夹杂同样具有类似的显著性质。结果表明,当0<κ<1,球夹杂中心将出现无穷大应力。而且,在无穷远拉荷载作用下,当0<κ<1/3,将出现空蚀现象;在无穷远压荷载作用下,当0<κ<1,将出现黑洞现象。更多还原

【Abstract】 A spherically uniform linear anisotropic spherical inclusion perfectly bounded in an infinite isotropic matrix is studied.When the system is subjected to a remote traction,analytical results show that remarkable natures appear in the spherical inclusion.It is demonstrated that when 0<κ<1 an infinite stress appears at the center of the inclusion.Furthermore,a cavitation is formed in the case of tension loading and 0<κ<1/3,and a blackhole comes into being when a compression loading is applied and 0<κ<1.更多还原
