摘要：

A new micro-tensile system has been developed to evaluate the mechanical properties of low-dimensional materials, such as fibers and films. The proposed system uses a magnet-coil force actuator to apply a tensile load on the material and a digital image correlation (DIC) method to measure the corresponding displacement and strain of the material. The system combines a supporting frame, a hanging spring, a magnet-coil, a permanent magnet, two specimen clamps, an adjustable stage and an image acquisition unit. To verify the proposed technique, experiments were conducted on two polymeric materials, silkworm silk and polyethylene oxide film containing nano-composite SiO2 (15%), to demonstrate the effectiveness of the system.
