Description In the present study, the application of the optimization methods used in Ansys is exposed, as well as the numerical analysis based on the Finite Element Method (FEM), for the detection of deformation and failure as well as elastic behavior. linear of different composite materials used on a rectangular laminar plate to be optimized; Each composite has inherent properties that classify and differentiate between them, as well as their coefficients of elasticity, stiffness and resistance. In the study, a script is created (code in APDL) that is executed in a graphical environment to show its displacement, deformation index and the volume, which is tried to minimize without violating the failure criteria established by Tsai-Wu. In addition, for optimization modes, the APDL code via script is executed in batch from the command line to save processing times. This script has been developed to optimize the rectangular plate and to be able to minimize the volume of the required material without exceeding the failure rate in order to determine which is the type of material that best adjusts to the linear elastic behavior.
En el presente estudio se expone la aplicación de los métodos de optimización usados en Ansys, así como el análisis numérico basado en el Método de Elementos Finitos (MEF), para la detección de la deformación y fallo así como el comportamiento elástico lineal de diferentes materiales compuestos usados sobre una placa laminar rectangular a optimizarse; cada composite tiene propiedades inherentes que las catalogan y diferencian entre ellos, así como sus coeficientes de elasticidad, rigidez y resistencia. En el estudio se crea un script (código en APDL) que se ejecuta en entorno grafico para mostrar su desplazamiento, índice de deformación y el volumen el cual se intenta minimizar sin que se viole el criterio de fallo establecido por Tsai-Wu. Además, para efectos de optimización, el código APDL vía script se ejecuta en modo batch desde la línea de comandos para ahorrar tiempos de procesamiento. Este script se ha desarrollado para optimizar la placa rectangular y poder minimizar el volumen del material requerido sin que sobrepase el índice de fallo para poder determinar cuál es el tipo de material que mejor se ajusta al comportamiento elástico lineal.
