Topological Derivative-based Optimization of Fiber-reinforced Structures, Coupled Thermoelastic Structures, and Compliant Mechanisms
The topological derivative of a functional quantifies the sensitivity with respect to an infinitesimal domain perturbations such as a hole, an inclusion, a source term, a crack, etc. In this thesis, topological derivatives ...
Shock Dynamics due to Downstream Pressure Perturbations: Idealization of Transonic Unstarted Cascade Flutter
Shock wave unsteadiness is an important phenomenon in high-speed aerodynamics. This
phenomenon is observed in many locations of high-speed vehicles, such as supersonic inlets,
ramjet engines, transonic airfoils, high-speed ...
Experimental and numerical study of mechanics and mechanisms of mode I fracture of a textured magnesium alloy
In recent years, magnesium alloys have gained increasing application in the automotive industry to achieve weight reduction in vehicle components which is crucial for enhancing fuel efficiency and meeting stringent emission ...
