For this, the dimensions of the crosslinking samples were modified taking a cure ratio as a reference, to determine the stress-strain, applying the Prony model which the Ansys-Mechanical platform offers. Experimental data was collected from the literature and a force test was performed on three different cylindrical samples (10:1 ratio) of PDMS with a curing agent. Consistent results of the modulus of elasticity as a function of time were obtained. Finally, using the Neo Hookean model, with consideration of hyperelastic material, and employing longer relaxation times, the results showed interesting findings in the parameters of total and directional deformation and other viscoelastic properties for this type of material.3309-1 - 3309-11openAccesspolymersmechanical propertiesfluidshydrodynamicscomputer calculationsviscosityelasticityArtigo de periódico314Sem PercentilSem Percentil CiteScore
