Robust bird-strike modeling using LS-DYNA
(2006)
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
(2010)
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 ...
Development of a combined interface and extended finite element method to predict delamination in composite structures
(2015-12)
For this work, an user-defined element (UEL) in ABAQUS was developed in conjunction with
a triangular traction separation law, as the Cohesive Zone Model, that combines the Extended
Finite Element and Cohesive Element ...
Finite element analysis of unexpected failure of lake-ice under loads moving at critical velocity
(2012-07)
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 ...
Characterization of bidimensional geometry through solid modeling software using A C++ interface
(2009)
In any design process a detailed description and communication of design ideas or specifications is essential. As part of the final design description are the engineering drawings that represent a detailed characterization ...
Data-driven life prediction model for bearing failure
(2009)
Throughout this work, a prognostic tool for the prediction of the remaining useful life of bearings using experimental data based on vibration data analysis is developed using MATLAB®. The experimental data used us that ...
Micro damage initiation and progression for isotropic and composites structure using strain invariant failure theory
(2015-09)
In this work, we focus our attention on initiation and progressive damage of isotropic
and composite structures using Strain Invariant Failure Theory (SIFT) at the micro-level.
The stress-based tools are very popular to ...
Micro-scale crack propagation using the eXtendend finite element method (XFEM)
(2015-12)
Crack propagation is a probably one of the most important subjects when it comes
to structural failure. Microstructural cracks are crucial because they could lead to catastrophic
failure. There has been some experimental ...
