Stress Concentration on PDMS: An evaluation of three numerical constitutive mod...
Sales, Flaminio; Souza, Andrews; Oliveira, Fallconny Rodrigues Sensato; Lima, Rui A.; Ribeiro, J.E.The examination of hyperelastic materials’ behavior, such as polydimethylsiloxane (PDMS), is crucial for applications in areas as biomedicine and electronics. However, the limitations of hyperelastic models for specific stress scenarios, with stress concentration, are not well explored on the literature. To address this, firstly, three constitutive models were evaluated (Neo-Hookean, Mooney-Rivlin, and Ogden) u...
Fire performance on the load bearing LSF walls
Oliveira, Fallconny Rodrigues SensatoThis work presents a numerical validation study of a load bearing light steel frame (LSF) wall structure in respect to full scale-test, to obtain the fire resistance of the wall. Three parametric studies were performed to evaluate the influence of the plasterboard’s thickness, plasterboard restriction and steel section in the fire resistance of load bearing LSF wall. Simplified studies were also developed in or...
