Shape memory alloys sma
WebbShape memory alloys (SMA) constitute a group of metallic materials with the ability to recover a previously defined length or a shape when subjected to an appropriate thermomechanical load (1). When there is a limitation of shape recovery, these alloys promote high restitution forces. WebbThe use of smart materials in the design of structures is emerging in the research community due to their unique ability to sense the environment and react upon thermal and/or mechanical stimulus. The main objective of this research study is to design innovative self-centering concrete beam-column connections reinforced using Shape …
