dc.description.abstractTHIS WORK AIMS TO DO A COMPUTATIONAL ANALYSIS OF THE INFLUENCE THAT GRADED POROSITY HAS ON THE ELASTIC MODULUS OF COMMERCIALLY PURE TI FOAMS. THIS ANALYSIS IS FOCUSED ON TI FOAMS FOR BIOMEDICAL USES. TWO KINDS OF GRADED POROSITY WERE CONSIDERED, LONGITUDINAL GRADED AND LATITUDINAL GRADED POROSITIES. EACH MODEL WAS MADE CONSIDERING THREE ZONES WITH DIFFERENT POROSITY LEVELS. THE ELASTIC MODULUS SIMULATIONS WERE MADE BY THE FINITE ELEMENT ANALYSIS (FEA) USING ANSYS SOFTWARE V19.3. THE RESULTS WERE COMPARED WITH EXPERIMENTAL DATA REPORTED IN THE LITERATURE. THE LONGITUDINAL AND LATITUDINAL GRADED POROSITY DISTRIBUTION MODELS WERE ANALYZED WITH EQUIVALENT POROSITY BETWEEN 30% AND 40% AND 20?50%, RESPECTIVELY. THE ELASTIC MODULUS VALUES DECREASED FROM 110 TO 38 GPA FOR THE LONGITUDINAL GRADED POROSITY, AND FROM 110 TO 36 GPA FOR THE LATITUDINAL GRADED POROSITY (0% AND 40% POROSITY, RESPECTIVELY). THOSE RESULTS SHOWED THAT LONGITUDINAL GRADED POROSITY WAS STIFFER THAN LATITUDINAL GRADED POROSITY MODELS FOR ALL POROSITY LEVELS.
