This dissertation advances Smoothed Particle Hydrodynamics (SPH) for solid dynamics, addressing hourglass instabilities and the simulation of thin structures under large deformations. Developed in three phases, it establishes a framework for accurate and efficient simulations. We introduce non-hourglass formulations for Total Lagrangian SPH (TLSPH) to improve stability and a TLSPH formulation for diverse materials. A reduced SPH dimension for plates and shells optimizes SPH for engineering applications.
