Stiffness and vibrational characteristics of SMS/DER331 composites with shape memory alloy long fibers

SMA-composites are an adaptive composite in which SMA elements are incorporated into fiber reinforced epoxy composites. Many researches have been done on investigating the properties of shape memory effect and superelastic influence in SMA composites. However, little information available on t...
