Shape memory materials
Webb18 juli 2024 · 1. Introduction Shape memory polymers (SMPs) are a class of smart materials which are able to “memorize” a permanent shape. SMPs can be fixed to one temporary shape under appropriate conditions, and also recover to their permanent shape in response to an external trigger, e.g. heat, light, or water, or magnetism. 1 Compared … WebbA new class of elastomers has unprecedented elongation and shape recovery abilities. The materials are said to break records for elongation and rules of elastomeric behavior. The materials are availa

The unfolding of antennas or other equipment can be driven by the shape memory effect [6]. The external stimulus can be an electric current that creates Joule-effects in the SMA. One of the first conceived industrial applications was in robotics where shape-memory (SM) foams were used to provide initial soft pretension in gripping. These SM foams could be subsequently hardened by cooling, making a shape adaptive grip. Since this time, the materials have seen widespread usage in, for example, the building industry (foam which expands with warmth to seal window frames), sports wear (helmets, judo and karate suits) and in some cases …

WebbIn this paper, the superelasticity effects of architected shape memory alloys (SMAs) are focused on by using a multiscale approach. Firstly, a parametric analysis at the cellular level with a series of representative volume elements (RVEs) is carried out to predict the relations between the void fraction, the total stiffness, the hysteresis effect and the … WebbCompleted a Ph.D. degree in 2024.

WebbShape memory effect samples were treated at 650 °C for 300 s and 500 °C for 300 s, with the first step contributing to material crystallization and the second step precipitation. Mechanical properties were analyzed by tensile testing (Zwick Roell Z.05, Germany) by using 0.5 N pre-load and a speed of 0.12 mm min −1 with a simple dog bone structure.
