“…The aim is to predict numerically the observed crack paths. The analysis of a 2D model of the physical tests is carried out using the X-FEM implementation developed by the authors [7][8][9]. The implementation is performed as a user's subroutine in the commercial code ABAQUS and can take into account crack face contacts along the loading cycle, which has been proved to be essential for the correct crack prediction.…”

In this work, the orientation and propagation of a crack in a fretting fatigue problem is analyzed numerically and correlated experimentally. The analysis is performed using a 2D model of a complete-contact fretting problem, consisting of two square indenters pressed onto a specimen subjected to cyclic fatigue. For the simulation, we use the extended finite element method (X-FEM), allowing for crack face contact during the corresponding parts of the fatigue cycle. The problem is highly non-linear and nonproportional and an orientation criterion is introduced to predict the crack direction in each step of the crack growth simulation. It is shown that the proposed criterion predicts crack orientation directions that are in good agreement with those found experimentally, in contrast to the directions found by application of conventional orientation criteria used in LEFM, such as the MTS criterion.

“…El proceso de cálculo basado en la simulación numérica se realiza a partir del software ANSYS ® Workbench en sus ediciones de 2017 y 2020 con su módulo específico SMART (Separating, Morphing, Adaptive and Remeshing Technology) Crack Growth que apoya su fundamento de cálculo en los principios del Método de los Elementos Finitos Extendido (XFEM 74 ), ampliamente utilizado en el proceso de fractura y crecimiento de grietas ( [289], [290]) y que adquiere cierta complejidad en su implementación por su alto coste computacional y dificultad de alcanzar la convergencia en algunas ocasiones. El mallado del modelo es un factor determinante en la obtención de resultados debido a la influencia en las bondades de los mismos.…”

The present project deals with the construction of a bicycle with a Bamboo structure, a cultivation plant preferably in the southwest of Mexico, however a bamboo cultivated in the Mexican Bajío was used. A transmission based on helical gears was also included, replacing the traditional transmission chain. Solidworks modeling was performed as well as finite element analysis to quantify bicycle safety factors as well as Von Mises efforts. Regarding the assembly and construction of the bamboo bicycle, different cuts of the plant's rods were made to adapt them to the tubular parts of the bicycle frame, in addition to the handlebar. The transmission was assembled with helical gears by coupling them with a power transmission shaft. Also tests were done, already armed the bike, both resistance and speed. And considering testing the transmission with gears.
