Abstract
Smart structural materials are a fundamental aspect that requires critical analysis in in structural engineering. This research contribution considers two vital crystal structures: Martensite and Austenite with their characteristic variations under different temperatures. From this research, it is seen the smart materials presents two vital features, which are distinguished from typical steels. The first one is the memory shape and the second one is super-elasticity. All of these properties can suit various applications in structural engineering e.g. dual actuators, self-rehabilitation and pre-stress bars. This research is purposed at analyzing the applications of smart materials in the field of structural engineering through the focus of relevant literature reviews, typical collection of data and major mechanic elements of smart materials. In axial tension evaluation, the curve for force and extension and the strain and stress curves of super-elasticity and Shape Memory Alloy (SMA) materials have been considered. The beam experiment with the superelasticity materials considered as the bars for reinforcement has been considered as well. This contribution provides the initial step of evaluation of the wide-range application of smart materials in the field of structural engineering.
Highlights
Considering the present state and development of technology for engineered materials, numerous materials have found their application in structural engineering and in handling the present deteriorating condition of infrastructure
Many novel cost-efficient and high-quality materials have been utilized in the field of structural engineering
The first stage is Austenite that is typically present at extremely high temperatures and the second one is Martensite In that regard, the remaining sections of the paper present a critical analysis of Smart Materials (SMs) in structural engineering
Summary
Considering the present state and development of technology for engineered materials, numerous materials have found their application in structural engineering and in handling the present deteriorating condition of infrastructure. Many novel cost-efficient and high-quality materials have been utilized in the field of structural engineering. This will allow us to gather basic knowledge concerning the smart materials before focusing on the major structural elements of SMs. The property of SMs tests have been based on the beam experiments, which are done to retrieve the data about the parameters of the materials utilized in this contribution and to effectively verify the wide-range application of SMs in structural engineering i.e. custom rehabilitations of cracked concrete segments.
