本文分析了无限远均匀热流作用下磁电弹性固体中的共线可渗透裂纹问题。分析依据的是扩展的斯特罗形式主义。给出了场强因子和裂纹内电磁场的简明表达式。结果表明，所有的场奇异性都与外加的电磁载荷无关，裂纹内的电磁场随裂纹线上的位置线性变化。
This paper analyzes the problem of collinear permeable cracks in a magnetoelectroelastic solid subjected to uniform heat flow at infinity. The analysis is conducted according to the extended Stroh formalism. Concise expressions are given for the field intensity factors and the electric–magnetic field inside cracks. It is shown that all the field singularities are independent of the applied electric–magnetic loads, and the electric–magnetic field inside cracks is linearly variable with position along the crack line.
