A three dimensional finite element analysis was completed for the analysis and redesign of a silicon seal. J-Integral calculations were completed to estimate the fracture toughness of the original design. A new design of the seal was created and a new finite element model created. The J-Integral calculations on the new design indicated an improvement of a factor of 8 times more durable for the new seal geometry. The new design was implemented into the medical machine and performance was found to be a favorable improvement over the original design.
