the stress strain curves show higher stress levels for higher cooling rates, Fig.2b. For\(\beta\) ≤ 30 K/s (red, blue and yellow graphs in Fig.2b) the compression tests showed barreling. In contrast, after water quenching (WQ, green curve in Fig.2b), the onset of shearing ...
Actuation stress versus actuation strain exhibiting actuation energy density of various active materials [125]. Active materials mostly demonstrate shape changes under the external fields such electric, optical, thermal and magnetic. Two significant criteria actuation energy density and frequency of active ...

through minimizing the total elastic energy as a function of homogeneous strain. This also means, for a polycrystalline magnetic material that is stress-free in all directions, the local magnetostriction (magnetic-field-induced strain)λxxis equal to the local spontaneous strain\(\varepsilon _{xx}...
