A study of DCT specimen in the verification of the influence of the geometric variation in the stress intensity factor

Palabras clave: Concrete, Disk-shaped Compact Tension Specimen, Fracture Mechanics, Stress Intensity Factor

Resumen

The objective of this work is to verify the influence of the stress intensity factor in the 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.
