Introduction In the 1970s, exterior bonded steel reinforcement was used sporadically to reinforce bridges to attain higher service load capacities. This steel post-strengthening system consisted of steel straps bonded with epoxies to the exterior of concrete beams. An alternative to the steel retrofit is woven carbon fiber reinforced polymer fabric applied in the same manner as steel. Carbon fi...

The problem: A new type of steel is known as Twining Induced Plasticity Steel, more commonly known as TWIP Steel. There is a general interest in using this type of steel in the automotive industry due to its unique material properties such as super toughness and super ductility, although its chemical properties also play a vital role. It has a high content of Mn (more than 25%) and about 3% Si ...
