With the aim of developing a thermo-mechanically-coupled large-deformation constitutive theory and a numerical-simulation capability for modeling the response of thermally-actuated shape-memory polymers, we have (i) conducted large strain compression experiments on a representative shape-memory polymer to strains of approximately unity at strain rates of 10 s and 10 s, and at temperatures rangi...

Abstract Background Ovarian vein embolization in pelvic varicocele is usually obtained using nitinol coils. These devices can not be used patients with proven nickel allergy. Case presentation Shape memory polymer a new embolic material available to interventionalists. A patient presented congestion syndrome requiring embolisation of the left ovarian vein. The target vessel consisted two twiste...

Material scientists predict a prominent role in the future for self-repairing and intelligent materials. Throughout the last few years, this concept has found growing interest as a result of the rise of a new class of polymers. These so-called shape-memory polymers by far surpass well-known metallic shape-memory alloys in their shape-memory properties. As a consequence of the relatively easy ma...
