| dcterms.abstract | A dual-stress spring-mass model coupled with rigid body modeling and the front tracking method is used to study the dynamic evolution of fabric surfaces and rigid structures in this dissertation. This computational framework is applied to the numerical study of the parachute deceleration process and the collision detection and handling. Both problems involve rigid body dynamics, as well as fabric dynamics which is described by a Lagrangian point-mass ensemble in FronTier++. The fluid-structure interactions with the parachute canopy and the parachutist for a realistic simulation of the air-deceleration system are presented. Moreover, we have included an impulse-based fail-safe method to handle fabric-fabric, fabric-rigid, and rigid-rigid collisions in our simulations. It is an universal algorithm to handle different types of collisions and the numerical experiments suggest its robustness. The computational efficiency of the framework is enhanced by the hybrid parallelization which combines Central Processing Unit (CPU) with the Graphics Processing Unit (GPU) computing technology. | |
