摘要
建立了形状记忆合金 ( SMA)纤维混杂复合材料矩形层合板振动响应的理论分析模型。首先提出简化的描述 SMA超弹性应力 -应变关系的分段线性化模型 ,采用多胞细观力学分析方法确定 SMA纤维混杂单层板的宏观力学性能参数 ;根据层合板力学分析方法建立 SMA纤维混杂正交对称铺设矩形板在超弹性相变阻尼影响下的横向振动响应求解的数学模型。
Theoritical analysis model of vibratory response of SMA fiber hybrid composite rectangular ply plate is presented in this paper.A piecewise linear hysteretic model is presented to describe the stress strain constitutive relationship of superelastic SMA.The multicell approach is used to obtain the mechanical properties of a hybrid SMA fiber ply.The governing equation of transverse vibratory response symmetric cross ply composite rectangular plate with SMA fibers embedded within the layers oriented in both directions is derived.The model incorporates with the effects of the damping from SMA phase transformation.Approximate solutions are available using mumerical methods based on the model.
