Granular Shape Memory Ceramics
Shape memory ceramics (SMCs) are burgeoning functional materials based on zirconia with a reversible, stress-inducible martensitic phase transformation. Compared to metallic shape memory alloys, SMCs have broader operating temperatures, higher critical stresses, and larger mechanical hysteresis …

Shape memory ceramics in small volumes
Shape memory ceramics rely on martensitic transformations which are similar to those found in metallic shape memory materials, but ceramics offer several advantages over metals such as higher operating temperatures and larger transformation stresses. However, polycrystalline shape memory ceramics …

Size Effects in Shape Memory Ceramics
Bulk shape memory ceramics (SMCs) are attractive for their high transformation temperatures and transformation stresses compared to shape memory metals but exhibit transformation-induced cracking due to mismatch stresses arising at the grain boundaries. Current strategies for mitigating cracking in …

Towards Crack-Resistant Polycrystalline Zirconia Shape-Memory Ceramics with Low Hysteresis
A new class of shape memory materials has been proposed based on zirconia-based ceramics, which offer higher work output, transformation temperatures, and possibly environmental resistance compared to metallic shape-memory alloys. Despite these potential benefits, two shortcomings have prevented …

Thermo-mechanical characterization of carbon-reinforced shape memory polymer
Shape memory materials (SMM) are those materials that possess the inimitable quality of remembering their shapes. They recover their original shapes upon exposure to external stimulus like heat, light, electric field, magnetic field, moisture etc. Types of SMMs include shape memory alloys (SMAs), …
