- Data-Driven Modeling of the Mechanics Behaviour of Architected and Soft Materials for Biomedical Applications(Instituto Tecnológico y de Estudios Superiores de Monterrey, 2022-06-13) García Ávila, Josué; Vargas Martínez, Adriana; dnbsmr; Martínez López, José Israel; Ramírez Cedillo, Erick Guadalupe; Cuan Urquizo, Enrique; School of Engineering and Sciences; Campus Monterrey; Rodríguez González, Ciro ÁngelThe most relevant human-related problems where mechanics has played an important role are primarily due to the intersection with multidisciplinary biomedical applications such as implants or flexible sensors. Recent advances in sophisticated materials with customized properties envision the manufacturing of the future, in which the materials' design is precisely tailored to the purpose of the application. The implementation of data-driven methods from highly dynamic, complex, and nonlinear contexts holds promise for addressing this difficult materials science problem. Engineering has found two classes of materials of particular interest as study objects, namely soft multifunctional materials and architected materials. However, these exhibit difficult mechanical behaviors to fully comprehend, including viscoelastic properties, high nonlinear deformation, anisotropy, apparent properties, unconventional deformation mechanisms, complex manufacturing processes, and hysteresis. Stretchable multifunctional materials are closely related to the study of multiphysics responses from the standpoint of manipulating behavior under specific energy spectrum field, whereas architected materials or mechanical metamaterials can provide structural tensegrity behavior in order to manipulate shape response conditions. This thesis sheds light and insight on some ideas inspired by discussions and reflections to understand these materials via a succesful project-based methodology and curiosity-driven research.
- Mechanical properties of tubular bioinspired metamaterials(Instituto Tecnológico y de Estudios Superiores de Monterrey, 2022) Palancares-Díaz, Jocelyn Sarai; CUAN URQUIZO, ENRIQUE; 345654; Cuan Urquizo, Enrique; puelquio/mscuervo; Román Flores, Armando; Jiménez Martínez, Moisés; Farfán Cabrera, Leonardo Israel; School of Engineering and Sciences; Campus MonterreyThis dissertation is concerned around the analysis of tubular bioinspired metamaterials and the relationship between their mesostructural characteristics in the cross sectional area and reticulated distribution and their mechanical characteristics under torsional and bending loads. Bioinspiration was taken from Cactaceae family to find cross sectional and void distribution inspiration, once the characteristics were selected a geometrical parameterization was performed. The mechanical characterization was done with the aid of FE models in COMSOL Multiphysics for bending and torsion. As validation some models were printed and tested under bending and torsion as well. The manufacturing of the samples used fused filament fabrication (FFF) with polylactic acid (PLA). Validation of the manufacturing using a microscope was done. The results from this study confirm the influence of the selected characteristics in the bending and torsional stiffness. Being the torsional stiffness being specially sensitive to changes in the cross sectional geometry while the bending stiffness was found to be best modulated by the allowance of the reticulated pattern to leave straight lines of material from one end to the other of the tubular structure.
- Desing and additive manufacturing of a transtibial prosthesis socket via powder bed fusion(Instituto Tecnológico y de Estudios Superiores de Monterrey, 2020-12-08) González Gallegos, Cynthia Pamela; Rodríguez González, Ciro Angel; tolmquevedo; García López, Erika; Segura Ibarra, Víctor; Escuela de Ingeniería y Ciencias; Campus Monterrey; Vázquez Lepe, Elisa VirginiaThis Thesis Project develops the Design and Additive Manufacturing of a transtibial socket made by powder bed fusion. The use of digital three-dimensional technologies is registered in the entire research, the stump modifications of sensitive and pressure areas are registered in the manner that the advantages of the PTB (Patellar Tendon Bearing) and TSB (Total Surface Bearing) socket types are merged to take advantages of their better features. Finally, the proposal of a Protocol that evaluates the prosthesis assembly in a biomechanical and emotional response is proposed to improve the socket adjustement.
- Evaluation of carbon fiber reinforced polymer composites produced by additive manufacturing for design guidelines(Instituto Tecnológico y de Estudios Superiores de Monterrey, 2018-05-11) Naranjo Lozada, Juan Miguel; Ahuett Garza, Horacio; Orta Castañon, Pedro; Kurfess, Thomas; Urbina Coronado, PedroThe use of additive manufacturing (AM) in many industries start to be a trend. The flexibility to manufacture complex geometries and the development of new AM materials and systems open new research fields. Recently, a family of technologies that produce fiber reinforced components has been introduced, widening the options available to designers. To find optimal structures using new AM technologies, guidelines for the design of 3D printed composite parts are needed. This thesis presents an evaluation of the effects that different geometric parameters have on the tensile properties of 3D printed composite. Two methods for manufacturing 3D printing composites, chopped and continuous fiber reinforcement (CFR), were analyzed. Parameters such as infill density and infill geometric patterns of chopped composite material, as well as fiber volume fraction and fiber arrangement of CFR composites are varied. The effect of the location of initial deposit point of reinforcement fibers on the tensile properties of the test specimens is also explored. From the findings, some design guidelines are proposed. Using these guidelines two application cases for Industry 4.0 systems were completed. A variation of the Rule of Mixtures (ROM) that provides a way to estimate the elastic modulus of a 3D printed composites is presented. Findings may be used by designers to define the best construction parameters for 3D printed composite parts.
