Análisis de falla en elementos de acero sometidos a cargas cíclicas mediante procesamiento de imágenes en software libre.

Abstract

The objective of this degree work is to analyze the fracture surface of steel elements subjected to cyclic loads during high service cycles, that is, fatigue failures. By creating a code and user interface for image processing in the Python programming language. The implemented software has two modules: preprocessing and image processing. The first module is made up of visual tools that allow the user to improve the visual conditions of the images for the identification of characteristic surface marks of the failure surface. The second module includes functions that help detect and frame relevant superficial aspects based on the information collected in the theoretical framework. Finally, a questionnaire is included that allows adding additional information about the failure process through the visual comparison of the results obtained in the two previous modules. The data and information are processed through the code developed to obtain analysis criteria, which must be interpreted to generate a fault diagnosis. So that certain aspects of the design and operating conditions of the element can be corrected, to prevent its breakage from happening again.
