在这份报纸，为 multiferroic 的三维的有限元素的明确的表达合成为它的短暂分析被开发并且实现进商业软件 ABAQUS。首先，一个特殊三维的八节点的稳固的元素被设计处理用橡皮做的合成的 multiferroic，压电，并且 piezomagnetic 材料。第二，为这个最新发达的元素的一个自定义子程序被实现进 ABAQUS。最后，双性人分层的 multiferroic 的短暂回答合成被使用直接时间集成方法计算。二个典型磁性的潜在的信号，高斯和 Ricker 脉搏，被用于与刺激的各种各样的时间持续时间合成。短暂反应能被输入实质地影响的导致的电场表演发信号，它能为最强壮的电的输出被调节。

英文摘要：

In this paper, a three-dimensional finite-element formulation for the multiferroic composite is developed and implemented into the commercial software ABAQUS for its transient analysis. First, a special three-dimensional eight-node solid element is designed to handle the multiferroic composite made of elastic, piezoelectric, and piezomagnetic materials. Second, a userdefined subroutine for this newly developed element is implemented into ABAQUS. Finally, the transient responses of a bi-layered multiferroic composite are calculated by using the direct time integration method. Two typical magnetic potential signals, Gauss and Ricker pulses, are applied to the composite with various time durations of excitation. The induced electric field shows that the transient response can be substantially influenced by the input signal, which could be tuned for the strongest electric output.
