A thermomechanical description of the martensitic phase transformation and the associated shape memory effect in polycrystalline shape memory alloys (SMAs) is presented. The rate-independent constitutive relations are derived in the stress-temperature space using a Lagrangian fo…
While traumatic aortic injury (TAI) and rupture (TAR) continue to be a major cause of morbidity and mortality in motor vehicle accidents, its underlying mechanisms are still not well understood. Different mechanisms such as increase in intraluminal pressure, relative movement of…
Al-Cu alloys have long been a subject of study due to their long history, high strength, and ease of manufacture. However, advanced characterization techniques have shown that the deformation mechanisms and precipitate-dislocation interactions are still not understood perfectly.…
This dissertation focuses on developing predictive models of the folding performance of multifield responsive structures and optimizing these structures based on design objectives. In particular, these origami-inspired structures incorporate smart materials such as electroactive…
