在线性全场磁电弹性理论的框架内，研究了导电和导磁压头作用于实际工业中广泛应用的磁电弹性材料表面时的磁电相互作用。运用算子理论、傅里叶变换和积分方程技术，显式地求解了二维混合边值问题。得到了两个半圆柱形理想导体压头的表面应力、电位移和磁感应强度及其强度因子的解析表达式。讨论了从两个半圆柱形压头到一个圆柱形压头的退化问题。数值分析揭示了多场载荷作用下两半圆柱压头之间的相互作用对接触行为的影响。
Within the theory of linear full-field magneto–electro–elasticity, magneto–electro interaction of two electrically-conducting and magnetically-conducting indenters acting over the surface of magnetoelectroelastic materials widely used in practical industries is examined. The operation theory, Fourier transform technique and integral equation technique are employed to address the two-dimensional, mixed boundary-value problem explicitly. The surface stresses, electric displacement and magnetic induction and their respective intensity factors are obtained in closed forms for two perfectly conducting semi-cylindrical indenters. Degradation from two perfectly conducting semi-cylindrical indenters to one single perfectly conducting cylindrical indenter is discussed. Numerical analyses are detailed to reveal the effects of the interactions between two semi-cylindrical indenters on contact behaviors subjected to multi-field loadings.
