RESUMEN The objective of this work is to verify the influence of the geometric variation in the stress intensity factor in a linear elastic fracture mechanics model. The model consists in a Disk-shaped Compact Tension specimen (DCT) of concrete material. The methodology considers a comparative study of an analytical approach from the literature and numerical simulations. These numerical simulations are performed in ANSYS Workbench program by the use of the Finite Element Method (FEM). The results show that the solutions obtained are satisfactory for the comparative study. El objetivo de este trabajo es verificar la influencia de la variación geométrica en el factor de intensidad de tensión en un modelo de mecánica de fractura lineal elástica. El modelo consiste en un espécimen de prueba compacta de tensión en forma de disco (DCT) de material de hormigón. La metodología considera un estudio comparativo de un enfoque analítico a partir de la literatura y de simulaciones numéricas. Estas simulaciones numéricas se realizan en el programa ANSYS Workbench mediante el uso del Método de Elementos Finitos (MEF). Los resultados muestran que las soluciones obtenidas son satisfactorias para el estudio comparativo.
