Magnetoelectric (ME) effect is a product property arising out of the interactions between the piezoelectric and the magnetostrictive phase. Multi-phase ME composites being multifunctional materials find use in myriad of applications. In this work, epoxy free two phase and three phase embedded ring ME composites have been fabricated by the press-fit technique. For a comparative study, three phase conventional epoxy bonded ring shaped composite of same dimensions have also been fabricated. Dynamic ME experiment has been conducted at room and elevated temperatures on all the prepared composites. It is shown that the epoxy free composite by virtue of the absence of epoxy shows a better resonant ME response at all temperatures. The significance of the Electromechanical Resonance (EMR) in the resonance behavior of the composites has also been highlighted. An analytical model in cylindrical coordinate system incorporating the temperature effects on the individual composite constituents and their interface coupling has been developed based on the concentric ring approach to predict the dynamic ME behavior of the epoxy free ring composite at different temperatures. The model has been further used to study the effect of volume fraction of the constituents on the ME response.

磁电效应是由压电相和磁致伸缩相之间的相互作用引起的产物性质。作为多功能材料的多相ME复合材料可用于多种应用。在这项工作中，通过压配合技术制备了无环氧的两相和三相嵌入式环ME复合材料。为了进行比较研究，还制造了相同尺寸的三相常规环氧粘合环形复合材料。已在室温和高温下对所有制备的复合材料进行了动态ME实验。结果表明，由于不含环氧，不含环氧的复合材料在所有温度下均表现出更好的共振ME响应。机电共振（EMR）在复合材料共振行为中的重要性也得到了强调。基于同心环方法，建立了一种结合了温度对复合材料各个成分及其界面耦合的影响的圆柱坐标系分析模型，以预测无环环氧复合材料在不同温度下的动态ME行为。该模型已进一步用于研究组分的体积分数对ME反应的影响。基于同心环方法，建立了一种结合了温度对复合材料各个成分及其界面耦合的影响的圆柱坐标系分析模型，以预测无环环氧复合材料在不同温度下的动态ME行为。该模型已进一步用于研究组分的体积分数对ME反应的影响。基于同心环方法，建立了一种结合了温度对复合材料各个成分及其界面耦合的影响的圆柱坐标系分析模型，以预测无环环氧复合材料在不同温度下的动态ME行为。该模型已进一步用于研究组分的体积分数对ME反应的影响。
