Robust bird-strike modeling using LS-DYNA
Throughout this work, bird-strike events are studied using three approaches in LSDYNA: Lagrangian, Arbitrary Lagrange Eulerian (ALE), and Smooth Particle Hydrodynamics (SPH). A simple one-dimensional beam centered impact ...
Mixed-mode fracture & fatigue analysis of rotating blades using the extended finite element method
This work focuses in the analysis of mixed-mode crack propagation and fatigue of two dimensional rotating blades using the Extended Finite Element Method (XFEM). A horizontal plate model simulates a UH-60 helicopter rotor ...
Finite element analysis of unexpected failure of lake-ice under loads moving at critical velocity
Through this work we predicted the unexpected failures of lake-ice under the effect of moving loads at critical velocity using finite element analysis. The main motivation was to solve the unexpected failure of the lake-ice ...
Stochastic fatigue failure prediction of adhesive bonded joints
This work describes the implementation of the Extended Finite Element Method (a partition of unity finite element method) for the study of fatigue failure of adhesive bonded joints when subjected to variable loading. The ...
Finite element simulations and optimization of Berdut linear motor for a novel elevator system
The present project has the objective to model and simulate a special linear motor known as a Berdut linear motor. The motor’s governing equations are derived from Maxwell's equation and Newton's law of motion. These ...
Generation and dynamic control of air microbubbles subjected to a complex 3D acoustic field
The purpose of this research is to verify that the translational movement of a microbubble in a complex three-dimensional geometry subjected to a standing acoustic field, can be predicted with the acoustic pressure gradient ...
