Constitutive Functions for Active Complaint Materials

在微流体和微机器人应用中，与使用活性聚合物的微器件相关的技术有着巨大的发展。这个SGER项目使用一个耦合的实验和分析的方法来提供必要的系统设计使用兼容的活性材料的组成描述。一种新型的双轴系统（BSAM）可以测量薄膜的有限变形，包括超弹性和粘弹性行为以及在机械载荷下的主动响应，通过测量局部变形和施加力的历史，同时控制拉伸空间中的轨迹。Criscione不变量将被用来描述超弹性势。

9909214There is a tremendous growth in technologies associated with microdevices usingactive polymers for microfluidics and microrobotics applications. This SGERproject uses a coupled experimental and analytical approach to provide theconstitutive descriptions necessary for systematic design using compliant activematerials. A novel Biaxial System for Active Materials (BSAM) is being developedto measure the finite deformations of thin films of such materials, includinghyperelastic and viscoelastic behavior and active response under mechanicalload, by measuring local deformation and applied force histories whilecontrolling the trajectory in stretch space. Criscione invariants will be usedto characterize the hyperelastic potentials.
