Abstract

Se presenta el estudio teórico para modelar en elementos finitos el sándwich del espejo de un bote de fibra menor a 15 metros de eslora, empleando un modelo matemático lineal isotrópico que se ajuste a las condiciones anisotrópicas del material. Esto se logra al definir las propiedades de la resina de fibra de vidrio empleada que sea representativo de la influencia de las fuerzas actuantes durante el planeo sobre la geometría de toda la embarcación. Se presenta la formulación del Método de Elementos Finitos sobre la cual trabaja el modelo matemático para definir las limitaciones de los resultados obtenidos. El ajuste isotrópico del material se calcula empleando las leyes de Halpin-Tsai, desarrollando su formulación matemática para conocer las restricciones del módulo de elasticidad que se ingresa como dato al programa de Elementos Finitos el cual es calculado de forma experimental para cada uno de los materiales del sándwich del espejo. ABSTRACT We performed a theoretical and experimental study to define the best way to model the finite element sandwich structure aft of a fiberglass boat less than 15 meters in length, using an isotropic linear mathematical model that fits anisotropic material conditions. This is done by defining the properties of the ship’s fiberglass resin structure, which is representative of the influence of the forces acting during the glide on the geometry of the entire vessel. Formulation of the Finite Elements Method is presented, which works on the mathematical model to define the limitations of the results obtained. Isotropic material adjustment is calculated using Halpin-Tsai laws, developing its mathematical formulation for restrictions of modulus data entered as the finite element program experimentally calculated for each of the sandwich materials. The best-fit mathematical presentation to the modulus of the composite tool justifies the calculation thereof.
