Enhancing Mechanical Behavior and Energy Dissipation in Fiber-Reinforced Polymers through Shape Memory Alloy Integration: A Numerical Study on SMA-FRP Composites under Cyclic Tensile Loading

Conventional fiber-reinforced polymers (FRPs) have a relatively linear stress–strain behavior up to the failure point. Therefore, they show brittle until Shape memory alloys, in addition having high ductility and good energy dissipation capability, are highly resistant corrosion performance against fatigue. using SMA fibers production of FRPs can be suitable solution solve problem conventional FRPs. integrated with polymeric matrix or without create new material called SMA-FRP. This study investigates effect different volume fractions (carbon, glass, aramid) (NiTi) super-elastic phase initial strain on SMA-FRP composites under cyclic tensile loading. Specimens designed reach target elastic modulus modeled OpenSees (v. 3.5.0) finite element software. Analyzing results shows that modulus, an increase fraction fibers, maximum stress, residual strain, hardening ratio reduced, ability capability stress increases. It was also observed increasing percentage increases reduces yield stress. In investigation type used construction composites, it found use larger composite ratio. addition, composites.
