9312207阿鲁达这项工作代表了验证光谱聚合物表征技术所需的规划活动，该技术是从变形的聚合物网络中原位表征取向参数的充分设备，适合在基于内部变量的聚合物本构模型中实施。用于测量弹性体在大应变变形过程中的偏振荧光的装置将用于实时表征各种变形状态。从模型弹性体网络获得的信息将被直接实施到本构模型中，作为监测取向状态的内变量。***

9312207 Arruda The work represents planning activities required for the verification of a spectroscopic polymer characterization technique as a sufficient apparatus for the in-situ characterization of orientation parameters from a deforming polymeric network, suitable for implementation into internal variable based polymer constitutive models. An apparatus for measuring the polarized fluorescence of elastomers during large strain deformations will be adapted for the real-time characterization of various deformation states. The information obtained from model elastomeric networks will be implemented directly into a constitutive model as internal variables monitoring orientation state. ***
