FEA is a numerical method for predicting the deformation of a part. Essentially, the part is broken down into a number of discrete entities or elements. A simultaneous analysis is performed on each individual element and the effect an element has on the neighboring elements, abaqus™, a commercially available finite element analysis (FEA) software program, was used for the modeling. FEA calculations were carried out to simulate the deformation of the edge seal for IGUs exposed to temperatures of -30°C (-22°F) and +60°C (+140°F). IGUs with galvanized steel and aluminum spacers were modeled with DOW CORNING 982 as the secondary sealant; units with stainless steel spacer were modeled with DOW CORNING 3-0117 sealant.
