This title addresses the hot topic of magneto-rheological (MR) materials in the field of smart materials research. The book introduces three MR materials: magneto-rheological fluids, magneto-rheological elastomers and a newly developed magneto-rheological plastomer, and explores their material properties, related modelling techniques and applications. The book offers insights into the relationships between the properties and characterisation of MR materials and their current and future applications, making it valuable reading for researchers, engineers and graduate students who work in the field of smart materials and structures.
