1. Sobre metodologias de modelagem computacional de propagação de trincas por fadiga em fuselagens aeronáuticas. / On computacional modeling methodologies of fatigue crack propagation in aircraft fuselages.
A methodology for modeling fatigue crack growth in pressurized, stiffened, thin shell structures is implemented within a software framework that consists of a fracture simulation code associated with a finite element analysis code. Crack trajetories are allowed to be arbitrary and are computed incrementally as a part of the simulation. Trajectories are repre

2. Uma proposta para a triangulação de Delaunay 2D e localização planar de pontos em OCaml
In this thesis, it is presented a planar point location algorithm. The algorithm was developed on top of two elements: - the method of slabs to divide the planar subdivision, is represented by a graph, allowing the fast identification of the region where the point being recalled is; - the Interval Multi-B-tree, a data structure derived from the B-tree, prepa

3. Finite element-based model for crack propagation in polycrystalline materials
In this paper, we use an extended form of the finite element method to study failure in polycrystalline microstructures. Quasi-static crack propagation is conducted using the extended finite element method (X-FEM) and microstructures are simulated using a kinetic Monte Carlo Potts algorithm. In the X-FEM, the framework of partition of unity is used to enrich
