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 ...

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 ...

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 ...

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 ...

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 ...

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 ...

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 ...

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 ...
